Question

Due to their low boiling points, lower alkanes are highly volatile.

• A. True
• B. False

Answer 1

The correct option is A

True

Volatility refers to the ability of a liquid to change into vapour state. Among alkanes, volatility decreases with increase in chain length as boiling point increases. Among isomeric alkanes, more the branching, lower is the intermolecular forces of attraction, greater is the volatility.
