22. The molecular weight of benzoic acid in benzene as determined by depression in freezing point method corresponds to
(1996, 1M)
(a) ionisation of benzoic acid
(b) dimerisation of benzoic acid
(c) trimerisation of benzoic acid
(d) solvation of benzoic acid
Show Answer
Answer:
Correct Answer: 22. (b)
Solution: In benzene, benzoic acid dimerises as :
$ \mathrm{C}_6 \mathrm{H}_5 \mathrm{COOH} \rightleftharpoons \frac{1}{2}\left(\mathrm{C}_6 \mathrm{H}_5 \mathrm{COOH}\right)_2 $
