ANSWER:
Solution 53P
Step 1 of 4
(a)
The provided reactants are (2S, 3S)-2-chloro-3-methylpentane and high concentration of methoxide ion. In this reaction the nucleophile is a strong nucleophile so reaction takes place through reaction mechanism.
The alkyl halide (2S, 3S)-2-chloro-3-methylpentane undergoes reaction with methoxideion to form (E)-3-methylpent-2-ene.
The reaction is as follows:
