Question

Name the following hydrocarbons?

Answer 1

`A.` `"cis-3-hexene"`

Explanation:

`B.` `"5-ethyldecane"`

For both molecules we find the LONGEST carbon chain. `B` is trying to trick into identifying the sidechains as the longest chain: clearly the longest alkyl chain is `10C` long. In solution, so far as anyone knows, the organic chain twists and turns; when we draw the molecule we should assume the maximum symmetry possible; i.e. a straight chain.
