28036 When acetic acid is dissolved in benzene its molecular mass

1 Decreases
2 Increases
3 Either increases or decreases
4 Suffers no change
ALDEHYDES, KETONES AND CARBOXYLIC ACID

28037 Benzoic acid has higher molecular weight in benzene and less in water because

2 It dissociates to a greater extent in benzene than in water
3 It associates in water and dissociates in benzene
4 It dissociates in water and associates in benzene
