Detailed explanation-1: -The amine group is located by the position number. Groups that are attached to the nitrogen atom are located using “N” as the position number. More complex primary amines are named with-NH2 as the amino substituent. Aromatic amines: named as derivatives of the parent compound aniline.
Detailed explanation-2: -Definition. Amine molecules have the general formula of R3-xNHx where R is a hydrocarbon group, and x is an integer with 0 < x < 3. Put another way, amines are derivatives of ammonia, NH3, in which one or more hydrogen atoms have been replaced by hydrocarbon groups.
Detailed explanation-3: -The substituent −NH 2 is called an amino group.
Detailed explanation-4: -The molecular formula of an amino group is NH2. Amines are derived from ammonia (NH3). Because nitrogen is electronegative (like oxygen), it pulls the electrons closer to it giving an amino group polar characteristics.
