Chapter 22, Problem 116AE

Interpretation Introduction

Interpretation: The isomer of ${\text{C}}_{\text{2}}{\text{H}}_{\text{4}}{\text{O}}_{\text{2}}$ which boils at the lowest temperature is to be stated.

Concept introduction: An isomer is defined as molecules having a same molecular formula but with a different structural arrangement of atoms within the formula. They do not have similar properties and functional group is also differing in their structures. The organic compounds are held together by intermolecular attractive forces which depend upon the surface area and hence, isomers exhibit different boiling points.

To determine: The isomer of ${\text{C}}_{\text{2}}{\text{H}}_{\text{4}}{\text{O}}_{\text{2}}$ which boils at the lowest temperature.
