CUET Chemistry

Acetic acid (CH₃COOH) dissolved in benzene shows abnormal molar mass. What happens and why?

A It dissociates, giving lower molar mass

B It associates (forms dimers), giving higher molar mass

C It remains unchanged, showing normal molar mass

D It decomposes, giving unpredictable molar mass

BITSAT Chemistry
