Question

NAME THE PRODUCT ALCOHOL OBTAINED WHEN ACETALDEHYDE REACTS WITH PROPYL MAGNESIUM CHLORIDE ​

Answer 1

Answer:

Explanation:

Grignard reagent with aldehydes reacts together to give organo-metallic compounds which on hydrolysis results in the formation of alcohol.

In the first step, formaldehyde was reacted with methyl magnesium bromide (Grignard reagent) which gives unstable adduct.

In the second step hydrolysis of product formed in step 1 gives us propan-1-ol as a final product.

The reaction can be given as follow:
