Acetamide is

The (major) product $(A)$ is:

How will you carry out the following conversion: $p$-nitroaniline to $3,4,5$-tribromonitrobenzene?

When $R-CO-NH_2$ is treated with $Br_2$ and $KOH$,it gives $R-NH_2$ as the major product. Which intermediate is involved in this reaction?

In the given reaction,what is the structure of the major product $X$?

Given below are two statements:
Statement $I$: Benzenediazonium salt is prepared by the reaction of aniline with nitrous acid at $273-278 \ K$. It decomposes easily in the dry state.
Statement $II$: Insertion of iodine into the benzene ring is difficult and hence iodobenzene is prepared through the reaction of benzenediazonium salt with $KI$. In the light of the above statements,choose the most appropriate answer from the options given below:
