Question

write the reagents required(1) CH = CH–CH2OH ?= CH2 =CH-CHO
(ii) CH3 -COOH ?= CH3 - CONH2​

Answer 1

Answer:

1.) Ag2O with NaOH

2.) Secondary amine with DCC (Dicyclohexylcarbodiimide)

Explanation:

1. Since Ag2O does not oxidises the double bond and it selectively oxidises only the alcohol group.

2. The second amine being highly basic tends to deprotonate the acid and form the highly unreactive and stable carboxylate anion and it does not yield the desired amide as the product, thus, Dicyclohexylcarbodiimide is used to aid the reaction to proceed and get the required amide as product.
