WebAlkyl group is formed by removing a hydrogen atom from the molecule of alkane. Alkanes are quite often represented as R-H and here R stands for alkyl group. The general formula of the alkyl group is CnH2n+1. The smallest alkyl group is CH 3 called methyl. A cycloalkyl is derived from a cycloalkane by removal of a hydrogen atom from a ring.
