Question

Intermediates formed during reaction of RCONH2 with Br2 and KOH are (A) RCONHBr and RNCO (B) RNHCOBr and RNCO (C) RNHBr and RCONHBr (D) RCONBr2

Tardigrade Admin · Accepted Answer

The reaction RCONH 2+ Br 2+ KOH arrow RNH 2 is known as Hoffmann-bromamide reaction. The mechanism of the reaction is <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/4037c75e018189a5c13ca2412e671f24-.png" /> This reaction is used in the descent of series, i.e. for preparing a lower homologue from a higher one.
