Question
How would you prepare cis-2-butene starting from propyne, an alkyl halide, and any other reagents needed? This problem can't be worked in a single step. You'll have to carry out more than one reaction.
Step 1
This can be done using an alkyl halide such as iodomethane (CH3I) in the presence of a base such as sodium amide (NaNH2). The reaction can be represented as follows: \[ \text{CH}_3\text{C}\equiv\text{CH} + \text{CH}_3\text{I} \rightarrow Show more…
