Answer 2

Question - Calculate the difference in the formulae and molecular masses for a)CH3OH and C2H5OH B)C2H5OH AND C3H7OH, and C)C3H7OH AND C4H9OH Is there any similarity in these three?

Answer -

The difference in formula and molecular masses of a)CH3OH and C2H5OH B)C2H5OH and C3H7OH and C)C3H7OH and C4H9OH is that of an alkyl group namely CH2. The molecular mass is 14 g/mol.

There exists similarity in these three, as they belong to a homologous series of alcohols. With the increasing number of carbon, their physical properties changes but the chemical properties remain the same.
