Answer 2

For preparation of pent-2-en-1-ol using $LiAlH_{4}$ methyl-pent-2-enoate will be used.

Explanation:

The reaction for the preparation of pent-2-en-1-ol using $LiAlH_{4}$ is as follows,

$CH_{3}CH_{2}CH=COOCH_{3} + LiAlH_{4} \rightarrow CH_{3}CH_{2}CH=CHCH_{2}OH$

This reaction is called esterification reaction in which ester is being reduce to alcohol using $LiAlH_{4}$ as a reducing agent.

$LiAlH_{4}$ is a strong reducing agent which is used to reduce carboxylic ester into alcohol.

In this process and aldehyde is procduced as an intermediate in the reaction but it can't be isolated.
