Which of the following molecules is a polar molecule?

A
B
C
Correct answer
D

Solution

A polar molecular is a molecular containing polar bonds, where the sum of all the bonds dipole moment is not zero.
In case of

H_{2} O

, the bonds are inclined at an angle, so the net dipole moment is non-zero. Hence,

H_{2} O

is a polar molecule while in all other cases the dipole moment are balanced, so the net moment is zero.

Hence, the correct answer is option: 'D'.
