(a) Select from the following the members of same homologous series :
[four structural (displayed) formulas of organic compounds labelled (1) to (4), each showing H, C, O atoms and bonds]
(b) What happens to (i) the melting point, and (ii) the solubility of compounds as the molecular mass of the compounds in a homologous series increases ?
Solution
(a) (1) and (4)
(b) (i) melting point increases with increasing molecular mass.
(ii) Solubility shows regular gradation/ decreases with increase in molecular mass.
