Question

How are the vapor pressure and boiling point of alkynes affected as the chain length increases? Both vapor pressure and boiling point decrease. Both vapor pressure and boiling point increase. Vapor pressure increases, and boiling point decreases. Vapor pressure decreases, and boiling point increases.

Answer 1

Vapor decreases boiling point increases.

Answer 2

The increased chain length increases boiling point and vapor pressure and boiling point are inversely related. Therefore:

Vapor pressure decreases, and boiling point increases.
