The Lewis electron-pair approach can be used to predict the number and types of bonds between the atoms in a substance, and it indicates which atoms have lone pairs of electrons. This approach gives no information about the actual arrangement of atoms in space, however. We continue our discussion of structure and bonding by introducing the valence-shell electron-pair repulsion (VSEPR) model (pronounced “vesper”), which can be used to predict the shapes of many molecules and polyatomic ions. Keep in mind, however, that the VSEPR model, like any model, is a limited representation of reality; the model provides no information about bond lengths or the presence of multiple bonds. The VSEPR Model The VSEPR model can predict the structure of nearly any molecule or polyatomic ion in which the central atom is a nonmetal, as well as the structures of many molecules and polyatomic ions with a central metal atom. The premise of the VSEPR theory is that elec...

I don't understand how having 0.128 moles of CO2 is the same as having 0.128 moles of C, and that having 0.1927 moles of H20, H2 just 0.1927 * 2? My logic is that the moles of C02 would be larger than just O (because CO2 is comprised of 2 elements rather than just one). And the moles of H20 would be a larger number than just H2 (because H20 is comprised of two elements rather than just one). Help! Thanks Think of like you have a single molecule of carbon dioxide. In that one molecule you have one atom of carbon and two atoms of oxygen. So for every molecule of carbon dioxide you have one carbon, a 1:1 ratio. Likewise every molecule has two oxygens, a 1:2 ratio. Remember that the mole is a unit that just measure the amount of stuff there is, just quite a large amount. So if we take those ratios from before and scale them up to larger number, we will still have the same ratio of carbon and oxygen atoms to molecules of carbon dioxide. For example, 1,000 carbon dioxide molecules will have 1,000 carbon atoms (1:1) and 2,000 oxygen atoms (1:2). Same logic applies to water and every other chemical. Hope that helps. using the masses of CO2 and H20, find the respective amounts of carbon, hydrogen, and oxygen through dimensional analysis. Use the method to find empiricle formulas (divide masses of elements by respective atomic masses, then divide them all by the smallest quotient). thats how many of each element is in the empirical formula The way you order elements in chemical form...

We have all heard of the ozone layer depletion, haven’t we? Due to vast global warming and the rapid increase of temperature on earth, the ozone layer of the stratosphere has a hole in it. This causes severe climate change and environmental damage. A pale blue gas with a molar mass of 47.99 g/ml, this molecular compound is often termed the activated oxygen. It can be useful for killing bacterial growth and also releases a pungent smell. Formed from the dioxide molecule, this molecule having three oxygen atoms is very crucial from the chemistry point of view. If you want to dive into his molecule, let us fasten our seat belts! Because I am going to make you travel through all the essential concepts and explanations related to bonding within ozone. Conclusion Lewis Structure To be very precise, Lewis Structure is the name given to the structural representation of a molecule. It is the diagrammatic layout for understanding the nitty-gritty of chemical bonding. A very essential concept of molecular chemistry, the following steps dictate how you can successfully draw Lewis Structure: Step 1 The initial step towards forming this structure is to find out the total number of valence electrons. ‘+’ stands for positive charge i.e giving away(loss) of electrons. ‘-’ stands for the gain of electrons, or in other words, negative charge. While calculating the valence electrons, we need to work with these two signs. Step 2 We now need to determine the central atom. How can we do so? We c...

Learning Outcomes • Compute formal charges for atoms in any Lewis structure • Use formal charges to identify the most reasonable Lewis structure for a given molecule • Explain the concept of resonance and draw Lewis structures representing resonance forms for a given molecule In the previous section, we discussed how to write Lewis structures for molecules and polyatomic ions. As we have seen, however, in some cases, there is seemingly more than one valid structure for a molecule. We can use the concept of formal charges to help us predict the most appropriate Lewis structure when more than one is reasonable. Calculating Formal Charge The formal charge of an atom in a molecule is the hypothetical charge the atom would have if we could redistribute the electrons in the bonds evenly between the atoms. Another way of saying this is that formal charge results when we take the number of valence electrons of a neutral atom, subtract the nonbonding electrons, and then subtract the number of bonds connected to that atom in the Lewis structure. Thus, we calculate formal charge as follows: [latex]\text[/latex] We can double-check formal charge calculations by determining the sum of the formal charges for the whole structure. The sum of the formal charges of all atoms in a molecule must be zero; the sum of the formal charges in an ion should equal the charge of the ion. We must remember that the formal charge calculated for an atom is not the actual charge of the atom in the molecule...

\( \newcommand\) • There is a tremendous variety of organic compounds which can be derived from carbon, hydrogen, and oxygen which is evident from the numerous previous sections discussing these compounds. If we include nitrogen as a possible constituent of these molecular structures, many more possibilities arise. Most of the nitrogen-containing compounds are less important commercially, however, and we will only discuss a few of them here. Amines may be derived from ammonia by replacing one, two, or all three hydrogens with alkyl groups. Some examples are Structures of methylamine, dimethylamine, and trimethylamine which is a primary amine, secondary amine, and tertiary amine respectively. The terms primary (one), secondary (two), and tertiary (three) refer to the number of hydrogens that have been replaced. Both primary and secondary amines are capable of hydrogen bonding with themselves, but tertiary amines have no hydrogens on the electronegative nitrogen atom. Amines usually have unpleasant odors, smelling “fishy“. The three methylamines listed above can all be isolated from herring brine. Amines, as well as ammonia, are produced by decomposition of nitrogen-containing compounds when a living organism dies. The methylamines are obtained commercially by condensation of methanol with ammonia over an aluminum oxide catalyst: First equation shows methanol reacting with ammonia to give methylamine and water. Next equation shows methanol reacting with methylamine to give d...

First of all, a terminology correction. While a nitrogen atom may be basic, a nitrogen atom itself won't be acidic, rather, the hydrogen atom attached to that nitrogen atom would be acidic, if at all. Now, whenever given an arbitrary compound, and this also holds true for atoms like carbon, oxygen, etc., here's what you need to do to determine the acidic and the basic atoms. What does acidity mean? Acidity means the ability to lose a proton from the compound. The higher the ability to lose a proton, the higher the acidity. If a compound, on losing a proton, forms a more stable conjugate base, it is considered more able to lose a proton. Hence, it is also more acidic (than other similar protons in that compound). What does basicity mean? Basicity means the ability to donate a lone pair of electrons to a proton. The higher the ability to donate a lone pair to a proton, the higher the basicity. If a compound, on donating a lone pair, forms a more stable conjugate acid, it is considered more able to donate a lone pair. Hence, it is also more basic (than other similar lone pairs in that compound). They both sound similar, don't they? That's because they're on the same underlying principle: a chemical species would want to accept a proton or donate a lone pair if the resulting species is more stable. Now, you can simply check for this in any given compound by deprotonating every H-atom and protonating every lone pair, while applying the simple rules of aromaticity, resonance, hy...
