Intermediates formed during reaction of RCNH2||O with Br2 and KOH are
A
RCONHBr and RNCO
B
RNHCOBr and RNCO
C
RNH-Br and RCONHBr
D
RCONBr2
Answer
RCONHBr and RNCO
Explanation
Solution
The correct option is(A): RCONHBr and RNCO. The process underlying the Hoffmann hypobromite reaction's mechanism.the mechanism involves the conversion of an amide (RCONH2) into an isocyanate (RNCO) through the reaction with bromine and sodium hydroxide (NaOH). This process results in the formation of RCONHBr (an intermediate) and eventually leads to the desired isocyanate product, RNCO.
