Question

Arranges the following molecules in order of increasing dipole moment: H2O, H2S, H2Te, H2Se.

Answer 1

Explanation:

Dipole moment is defined as the measurement of the separation of two opposite electrical charges.

$H_{2}O$ is a bent shaped molecule with a dipole moment of 1.87.

$H_{2}S$ is also a bent shaped molecule with a dipole moment of 1.10.

$H_{2}Te$ is a also a bent shaped molecule and has a negligible dipole moment.

$H_{2}Se$ has a dipole moment of 0.29.

Therefore, given molecules are arranged according to their increasing dipole moment as follows.

        $H_{2}Te$ < $H_{2}Se$ < $H_{2}S$ < $H_{2}O$
