Current Question (ID: 8222)

Question:

$\text{Among water, ether, and acetone, water has the maximum boiling point and ether has the minimum boiling point. The correct order of vapour pressure of water, acetone and ether at } 30^\circ\text{C} \text{ is-}$

Options:

1. $\text{Water}<\text{ether}<\text{acetone}$
2. $\text{Water}<\text{acetone}<\text{ether}$
3. $\text{Ether}<\text{acetone}<\text{water}$
4. $\text{Acetone}<\text{ether}<\text{water}$

Solution:

$\text{Hint: Magnitude of vapour pressure and boiling point are inversely proportional to each other}$ $\text{The given compounds are}$ $\text{Water} \quad , \quad \text{acetone}, \quad \text{ether}$ $(\text{Maximum b p}) \quad \quad \quad \quad \quad (\text{Minimum b p})$ $\text{Greater the boiling point, lower is the vapour pressure of the solvent.}$ $\text{The boiling point of water is } 100^\circ\text{C}, \text{ acetone boiling point is } 56^\circ\text{C}, \text{ and ether boiling point is } 34.6^\circ\text{C}. \text{ Hence, the correct}$ $\text{order of vapour pressure will be-}$ $\text{Water}<\text{acetone}<\text{ether}.$
