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

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

Options

A $\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}$
B $\mathrm{CH}_3 \mathrm{OH}$
C $\mathrm{H}_2 \mathrm{O}$
D $\mathrm{C}_6 \mathrm{H}_6$

Correct answer

C. $\mathrm{H}_2 \mathrm{O}$

Step-by-step solution

More is the hydrogen bonding; more is the surface tension. Thus, order of surface tension is:

\mathrm{H}_2 \mathrm{O}>\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}>\mathrm{CH}_3 \mathrm{OH}>\mathrm{C}_6 \mathrm{H}_6
