what are alkyl, aryl, aliphatic and aromatic groups?
477755
Aromatic groups are also those which obey Huckels rule, and contain 4n+2 (and n>1) electrons in the ring.\n\nBenzene is aromatic since it has 6 electrons, which solves the equation for when n = 1.\n\nAlkyl/aliphatic groups are fully saturated carbon chains, which can be either cyclic, non-cyclic, branched or unbranched.  Alkyl and aliphatic mean the same thing.\n\nAryl is generally used to describe benzene derivatives.

Heterocyclic amines.  Nicotine also contains a pyridine (aromatic heterocyclic ring).  \n\nThe word alkoloid means "a substance with a basic charge."  This comes from the amine.\n\nLook at the structures at the sites below:

Alkylating agents add alkyl groups to electronegative groups, cross-linking guanine nucleotides in DNA.\n\nExamples: Busulfan, cyclophosphamide, carmustine.
