Question

Di-imide $\left(N_2{h}_4\right)$ is used to reduce double bond of:

• A. $-\underset{|}{C}=O$
• B. $-C\equiv N$
• C. $-N{O}_2$
• D. $-CH=CH-$

Answer 1

The correct option is A $-\underset{|}{C}=O$

For question 1, $N_2{H}_4$ is called as hydrazine which is an important reducing agent in Wolf-Kishner reaction and converts carbonyl functionalities into methylene groups. So, option a, must be the answer.
