When aniline is nitrated with nitrating mixture in ice cold condition, the major product obtained is
p-nitroaniline
2,4-dinitroaniline
o-nitroaniline
m-nitroaniline
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 NH2 group is protected by acetylation and then nitrated with nitrating mixture, p-isomer is the main product.
Ribose and 2-deoxyribose can be differentiated by
Fehling's reagent
Tollen's reagent
Barfoed's reagent
Osazone formation
