Expert Solution
Step 1
At boiling point the vapour pressure of liquid and pressure exerted by the surrounding are equal. The compounds with high intermolecular forces will have high boiling point. Boiling point in hydrocarbons increases with increase in the number of carbon atoms and branching.
Gaseous molecules present above the liquid in sealed container will exert pressure on that liquid. This pressure is termed as vapor pressure. Vapor pressure increases with temperature. If molecules with strong intermolecular forces will exert lower vapor pressure while the molecule with weak intermolecular forces will exert higher vapor pressure.
