Question

The boiling points of $C_6H_6$, $CH_3OH$, C6H5NH2 and C6H5$NO_2$ are 80°C, 65°C, 184°C and 212°C, respectively. Which of the following will have the highest vapour pressure at the room temperature?

Prashant Kotian · Accepted Answer

Correct answer: B. Vapour pressure at a given temperature is inversely ∝ boiling point. has the lowest boiling point (65°C), so it has the highest vapour pressure at room temperature.
