Polarity in a molecule and hence the dip...

Polarity in a molecule and hence the dipole moment depends primarily on electronegativity of the constituent atoms and shape of a molecule. Which of the following has the highest dipole moment?

A

`CO_(2)`

B

HI

C

`H_(2)O`

D

`SO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
c) `CO_(2)` being symmetrical has zero dipole moment.

Among HI, `SO_(2)` and `H_(2)O` dipole moment is highest for `H_(2)O` as in it the central atom contains 2 lone pairs.
