Question
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
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.
