Question

Which is not a characteristic of haloalkanes?

• A. Alkyl halides are colourless in pure form
• B. Alkyl bromides and iodides develop colour when exposed to light
• C. Many volatile halogen compounds have sweet smell
• D. Intermolecular forces are less as compared to hydrocarbons

Answer 1

The correct option is D Intermolecular forces are less as compared to hydrocarbons

Haloalkanes are polar molecules, and polarity is due to the difference of electronegativity between $R$ and $X$ bonds. Hence intermolecular forces of attraction of haloalkanes are more compared to non polar hydrocarbons.
