The Physical Properties of Halogenoalkanes

The Physical Properties of Halogenoalkanes

·         Contains the functional group C-X, where X is a halogen (F₂,Cl₂,Br₂,I₂)

·         The general formula is: C_nH_2n+1X

·         The C-X bond in halogenoalkanes is polar because the halogen atom is more electronegative that the C atom

·         2 types of intermolecular forces between halogenoalkanes: Van der Waals’ and Permanent dipole-dipole interactions

·         The molecular forces of attraction due to Van der Waals’ forces increases as the M_r increases, e.g. the boiling point of chloroalkanes increases as the chain length increases

·         Although permanent dipole-dipole…
