Question

How many reagents from the followings occurs below Reaction:

i) \(H_3PO_2\)
ii) \(CH_3CH_2OH\)
iii) \(H_2O\)
iv) \(H_3PO_3\)
Me + N,a- Me

• A. $4$
• B. $3$
• C. $1$
• D. $2$

Answer 1

The correct option is D $2$

$H_{3}P{O}_2$ is the reagent that converts $N_2^{+}C{l}^{-}$ group into H. During this process $N_2$ and $HCl$ gas are released.

Diazonium salt with ethanol also replace $N_2$ by H atom.
Hence, (c) option is correct.
