When aniline is nitrated with nitrating mixture in ice cold condition, the major product obtained is :

• A. p-nitroaniline
• B. 2,4-dinitroaniline
• C. o-nitroaniline
• D. m-nitroaniline

Answer 1

The correct option is A p-nitroaniline

Direct nitration of aniline with nitric acid gives a complex mixture of mono, di- and tri- nitro compounds and oxidation products. If $-{NH}_2$ group is protected by acetylation and then nitrating mixture, p-isomer is the main product.
