Question

write a molecular formula of first two members of homologous series with functional group OH

Answer 1

Here's your answer

CH3OH. =methanol

C2H5OH = Ethanol

Answer 2

Explanation:

The first two members of homologous series with functional group OH are:

1. Methanol

In the molecular formula of methanol there are 1 carbon atom and , 3 hydrogen atoms and  one oxygen atoms.;$CH_3OH$

2. Ethanol

Molecular formula of ethanol will be $C_2H_5OH$. There are two carbon atoms , 5 hydrogen atoms and 1 oxygen atom.
