Alkyl Groups Alkanes can be described by the general formula C nH 2n +2. An alkyl group is formed by removing one hydrogen from the alkane chain and is described by the formula C nH 2n +1. The removal of this hydrogen results in a stem change from -ane to -yl. Take a look at the following examples.

What is the structure of alkanes?

Alkanes are organic compounds that consist of single-bonded carbon and hydrogen atoms. The formula for Alkanes is CnH2n+2, subdivided into three groups – chain alkanes, cycloalkanes, and the branched alkanes.
