Chapter 13, Problem 13.69AP

Interpretation Introduction

Interpretation:

Given compounds has to be ranked in increasing order of boiling point.

    ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CH(CH}}_{\text{3}}{\text{)}}_{\text{2}}{\text{, CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CO}}_{\text{2}}{\text{H, and CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{COCH}}_{\text{3}}$

Concept Introduction:

Boiling point of a substance is the temperature at which the liquid phase gets converted into vapor state.  Carboxylic acid, esters and alcohols are polar compounds.  This is because they have polar groups present in them.  Carboxylic acid possess intermolecular hydrogen bonding. Ester and carboxylic acid contains polar carbonyl group.

If there is a greater intermolecular force present in the compound, then the boiling point will be more as more energy will be required to overcome the intermolecular forces.
