Tardigrade Admin · Accepted Answer

Hofmann bromamide reaction: this method is used for the preparation of any 1° amine as well as aniline. During the reaction amide is treated with Br 2 and alkali (KOH) to get primary amine. This reaction is used to descend the series in which carbon atom is removed as carbonate ion ( CO 32-) reaction is given as <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/708207d864330017000e3581a672c965-.png" />
