Alkyl groups:
Alkyl groups that are represented as CnH2n+1 are alkane substituents of a complex molecule. Simple alkyl groups can be pointed out in skeletal form, or like CH3, CH2CH3, CH2CH2CH3, et cetera.

Figure: Drawings of an alkyl substituted cyclohexane.
Note: how the CH3 groups have been written in Diagram. The structure in Figure (a) is more correct as compared to the structure in Figure (b) because the bond displayed is between the carbons.
