The surface tension of which of the following liquid is maximum?

A

`H_(2)O`

B

`C_(6)H_(6)`

C

`CH_(3)OH`

D

`C_(2)H_(5)OH`

Text Solution

Verified by Experts

The correct Answer is:
A
Surface tension of `H_(2)O` is maximum due to maximum hydrogen bonding in comparison to
`C_(6)H_(6),CH_(3)OH,C_(2)H_(5)OH`.
The order of H-bonding is
`H_(2)O gt CH_(3)OH gt C_(2)H_(5)OH`.
(Benzene does not form H-bond).
