. In a homologous series, the molecular mass of the fourth member is 72 u. What will

be the molecular mass of 10th member of the series?​

Answer 1

Explanation:

(i) In term of molecular mass each successive member in a homologous series differ by molecular mass of 14u by the preceding member.

(ii) Two consecutive homologues differ by 1 carbon atom and 2 hydrogen atoms in their molecular formulae.
