The magnitude of surface tension of liquid depends on the attractive forces between the molecules. Arrange the following in increasing order of surface tension : water, alcolhol (C_(2)H_(5)OH) and hexane [CH_(3)(CH_(2))_(4)CH_(3)].

1.	The magnitude of surface tension of liquid depends on the attractive forces between the molecules. Arrange the following in increasing order of surface tension : water, alcolhol (C_(2)H_(5)OH) and hexane [CH_(3)(CH_(2))_(4)CH_(3)].
Answer» Solution :Attractive forces are MINIMUM in hexane (only London forces). Hydrogen bonding in `H_(2)O` is STRONGER than that in `C_(2)H_(5)OH`. Hence the order of surface tension is : hexane `lt` alcohol`lt`water.
