Question

The critical temperature of water is higher than that of $O_2$ because $H_{2}O$ molecule has

• A. Fewer electrons than oxygen
• B. Two covalent bonds
• C. V-shape
• D. Dipole moment

Answer 1

The correct option is D

Dipole moment

Critical temperature of water is more than $O_2$ due to its dipole moment

(Dipole moment of water = 1.84 D; Dipole moment of $O_2$=zero D).
