The molecular mass of acetic acid dissolved in water is 60 and when dissolved in benzene it is 120. This difference in behaviour of `CH_(3)COOH` is because

Options

A. Water prevents association of acetic acid
B. Acetic acid does not fully dissolve in water
C. Acetic acid fully dissolves in benzene
D. Acetic acid does not ionize in benzene

Answer

A

Explanation

Water forms hydrogen bonding with acetic acid and prevents the association of molecules to form dimers as it happens in benzene solution. So the observed molecular mass in benzene solution is `2xx60=120`.
