$1.22 gm C_{6} H_{5} COOH$ is added into 100 gm of acetone, elevation in B.P. is found to be 0.17 . If $K_{b}$ (acetone) $= 1.7 K - Kg mol^{- 1}$ then select the incorrect options

Options:(select one or more)

Answer:

A, D

Solution:

Question Explanation:

The question asks about incorrect options.

Concept:

This question is based on the elevation in boiling point.

Solution:

The formula for elevation in boiling point is:

$Δ T = i \cdot K_{b} \cdot m$

$0.17 = i \times 1.7 \times \frac{\frac{1.22}{122}}{100} \times 1000$

If $i = 1$ , then no association or dissociation takes place.
