The critical temperature of water is higher than that of `CO_(2)` because the `H_(2)O` molecular has

A

fewer electrons than `O_(2)`

B

two covalent bonds

C

V-shape

D

diople moment.

Text Solution

Verified by Experts

The correct Answer is:
D
Attractive forces in `H_(2)O` molecules are more than in `CO_(2)` molecules because of greater polarity (dipole moment).
