Glucose or sucrose are soluble in water but cyclohexane or
benzene (simple six membered ring compounds) are insoluble in
A glucose molecule contains five
-OH groups while a
sucrose molecule contains eight
-OH groups. Thus,
glucose and sucrose undergo extensive H-bonding with water.
Hence, these are soluble in water.
But cyclohexane and benzene do not contain
-OH groups. Hence,
they cannot undergo H-bonding with water and as a result, are
insoluble in water.
