Chapter 3, Problem 3G.8E

Interpretation Introduction

Interpretation:

Match of surface tension of molecule below has to be determined.

  ${\text{H}}_{\text{2}}{\text{O, CH}}_{\text{3}}{\left({\text{CH}}_{\text{2}}\right)}_{\text{4}}{\text{CH}}_{\text{3}}{\text{, C}}_{\text{6}}{\text{H}}_{\text{6}}{\text{, CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{OH, CH}}_{\text{3}}\text{COOH}$

Concept Introduction:

Dipole-dipole interactions come into play when partial charges of different dipoles interact with each other. Higher the polarity between molecules more will be dipole-dipole interactions between them and vice-versa. Surface tension is property of liquid that reflects energy require to expand surface of liquid. This surface area is hard to expand or more energy is required if intermolecular forces are stronger.
