WebThere are four major types of nitrogen compounds. These are Amino (-C-NH 2), Nitro (-C-NO 2), Nitriles (-CN), and Amides ( –CONH 2). Amines. An amine is basically a functional group with a nitrogen atom bearing a lone pair of electrons. Amines are formed when one or more hydrogen atoms of an ammonia molecule are replaced by alkyl or aryl groups. The reduction of nitro compounds are chemical reactions of wide interest in organic chemistry. The conversion can be effected by many reagents. The nitro group was one of the first functional groups to be reduced. Alkyl and aryl nitro compounds behave differently. Most useful is the reduction of aryl nitro compounds. funny hermione memes https://mintpinkpenguin.com
