Assertion is true and reason is false.
Alcohols are functional groups in chemistry, characterized by the presence of -OH group.
Homologous series refers to the family of particular group, with parent group or molecule remaining the same.
In each successive homologous series, one alkyl group is added.
Homologous series of alcohols can be written with the help of formula - C(n)H(2n+1)OH. In this formula, n represents number of atoms.
For the value 2, C2H5OH will form while for 3, C3H7OH and so on. Alkyl group added in question is CH2. The weight of CH2 is 14.
