Methane, which is composed of carbon and hydrogen, lacks functional groups and is a gas at room

temperature. Upon replacing one of the hydrogen atoms with a hydroxyl group, methane is converted
to methanol, which is a liquid at room temperature. Explain the reason behind this difference in
physical properties.What will be an ideal response?


Concepts to Consider: Polar nature of methanol compared to methane is due to polar hydroxyl group;
polarity of methanol allows formation of hydrogen bonds and increases cohesiveness of this chemical.
