Which of the following statement(s) is/are incorrect in case of Hofmann bromamide degradation ?

A

Reaction is useful for decreasing length of carbon chain by one carbon atom

B

It gives tertiary amine

C

It gives primary amine

D

Text Solution

Verified by Experts

The correct Answer is:
B

Statement B is incorrect in case of Hofmann bromamide degradation . This is used to synthesis primary amine.
In this reaction, amide on reation with `Br_(2)` in an aqueous or ethanolic solution of `NaOH` give `1^(2)` amine with one C atom less than that present in the amide.
`RCONH_(2) + Br_(2) + 4KOHoverset(Delta)rarrunderset(1^(@) "amine")(RNH_(2)) + 2KBr +K_(2)CO_(3) + 2H_(2)O`
