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_2O`

D

`SO_2`

Text Solution

Verified by Experts

The correct Answer is:
C
`CO_2` being symmetrical has zero dipole moment

Among HI, `SO_2 and H_2O` dipole moment is highest for `H_2O` as in it the central atom contains 2 lone pairs
