Question

A,B and C are member of a homologous series , there melting points are -1830C,-1380C,-1300C respectively. Among these :-. i) which member will have least number of carbon atoms. ii) Which member will have maximum number of carbon atoms

Answer 1

In a homologous series with the increase in number of carbon atom,there is an increase in the molecular mass of the compound.when there is an increase in molecular mass the melting point increases( I.e down the homologous series).

1) the answer is C.

2) the answer is A
