Question

First product of the reaction between \(RCHO\) and \(NH_2NH_2\):

• A. \(RCH = NNH_2\)
• B. \(RCH = NH\)
• C. \(RCH_2NH_2\)
• D. \(RCON_3\)

Answer 1

The Correct Option is A

This is a straightforward condensation reaction that occurs through the elimination of water. When an aldehyde, denoted as \(RCHO\), reacts with hydrazine \((NH_2NH_2)\), it results in the formation of a hydrazone, represented as \(RCH=NNH_2\).

So, the correct option is (A): \(RCH = NNH_2\)
