Question

Assertion: In a homologous series of alcohols, the formula for second member is CzH5OH
and the third member is C3H7OH.
Reason: There is a difference between the molecular masses of the two consecutive
members of a homologous series.​

Answer 1

Answer :

Two statements are given, one label assertion A and the other label reason R.

Assertion (A) =in a homologous series of alcohols the formula for the second member is C2H5Oh and the third member is C3H7OH.

Reason (R) =the difference between the molecular masses of the two consecutive members of a homologous series is 144.

Hope these answer helps you...
