(a)
Answer to Problem 30A
The name of the above compound is 2-pentene.
Explanation of Solution
The principle chain contains five carbon atoms and one double bond between C2 and C3. So, the name of the above compound is 2-pentene.
(b)
Interpretation:
The name of the given alkene has to be described.
Concept Introduction:
Alkenes are acyclic or cyclic unsaturated hydrocarbons containing at least one carbon-carbon double bond (C=C) and the general molecular formula CnH2n (where n = number of carbon atoms). Simplest alkene among all is ethylene C2H4 which contains one carbon-carbon double bond.
Alkenes can also be two types-
- Unbranched alkenes
- Branched alkenes

Answer to Problem 30A
The name of the above compound is 3,4,5-trimethylhept-1-ene.
Explanation of Solution
The principle chain contains seven carbon atoms, three methyl substituents at C3, C4 and C5 and one double bond between C1 and C2. So, the name of the above compound is 3,4,5-trimethylhept-1-ene.

- b) Certain cyclic compounds are known to be conformationally similar to carbohydrates, although they are not themselves carbohydrates. One example is Compound C shown below, which could be imagined as adopting four possible conformations. In reality, however, only one of these is particularly stable. Circle the conformation you expect to be the most stable, and provide an explanation to justify your choice. For your explanation to be both convincing and correct, it must contain not only words, but also "cartoon" orbital drawings contrasting the four structures.
