Chapter 8, Problem 8.11P

Interpretation Introduction

Interpretation:

Reason for molecular weight of perfluromethylcyclohexane is three times that of methylcyclohexane, but its boiling point is lower than that of methylcyclohexane has to be identified.

Concept introduction:

Density of haloalkanes is more as halogens have larger mass-to-volume.

The carbon-halogen bond of alkyl halide is polarised.

Dipole moment increases, as the electronegativity of halogen and bond length increases.

Haloalkanes in liquid state has a combination of attractive forces, termed as van der Waals forces.
