- step up the series
- step down the series

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Hoffmann bromaraide reaction converts acid amides to primary amines :
$\underset{\text{Acid amide}}{{RCONH_{2}}}+Br_{2}+4KOH \to \underset{\text{$1^{\circ}$ amine}}{RNH_{2}}+2KBr+K_{2}CO_{3}+2H_{2}O$
The $1^{\circ}$ amine formed has one carbon atom lesser than that present in acid amide
$\underset{\text{Acid amide}}{{RCONH_{2}}}+Br_{2}+4KOH \to \underset{\text{$1^{\circ}$ amine}}{RNH_{2}}+2KBr+K_{2}CO_{3}+2H_{2}O$
The $1^{\circ}$ amine formed has one carbon atom lesser than that present in acid amide

Concepts Used:
Amines
Amine is a type of compound which is derived from ammonia (NH3). According to Organic chemistry, they are basically classified as the functional groups of the organic nitrogen compounds that contain nitrogen atoms with a lone pair.
Amine - Types
Primary Amines:
It is formed when one hydrogen atom in ammonia is substituted by an alkyl or aromatic group. Amino acids and methyl amine are the best examples that why aromatic amines include aniline.
Secondary Amines:
Amines that have two organic substitutes either alkyl or aryl ones or both and are bound to the nitrogen together with one hydrogen are termed as secondary amines. For Example, Dimethylamine.
Tertiary Amines:
Tertiary Amines are the amines where the nitrogen consists of three organic substitutes. For example, Trimethylamine and EDTA.
