प्रश्न
Write the chemical formula of two consecutive homologous of organic compounds having functional group - OH.
What happens to the (i) boiling point and (ii) solubility of organic compounds of a homologous series as the molecular mass increases?
उत्तर
The general formula of the homologous series of the compound -OH group is CnH2n+1OH.
The two consecutive homologous are: Methanol (CH3OH) and ethanol (C2H5OH).
- As the molecular mass increases in homologous series, the boiling point also increases.
- The solubility of an organic compound decreases with increase in molecular mass.
