Document Summary
Questions ch. 3: 75, 77, 79, 81 ch. 26: 1, 3, 17, 21, 25, 31, 33. We talk about organic the most because there are more of them. Carbon likes to bond to itself in big huge longs chains which is why it is so special and why organic chemistry is so special. Structural formula: with the sticks to show where everything is relative to each other. Condensed: same as structural get rid of the sticks. Constitutional isomers or structural isomers have the same molecular formula but a different connection scheme for the atoms. Halides as functional groups: they are named as substituents (fluoro, chloro, bromo, iodo, chain rules are the same as adding methyl groups, still an alkane. If a molecule has 2 functional groups it should be named with the highest priority group determining the type, the other group will be a substituent.
