Each of the following options contains a set of four molecules. Identify the option(s) where all four molecules possess permanent dipole moment at room temperature.

A

`NO_(2), NH_(3), POCl_(3),. CH_(3)Cl`

B

`BF_(3), O_(3), SF_(6), XeF_(6)`

C

`BeCl_(2),CO_(2),BCl_(3),CHCl_(3)`

D

`SO_(2), C_(6)H_(5)Cl, H_(2)Se, BrF_(5)`

Text Solution

Verified by Experts

The correct Answer is:
A, D
Unsymmetrical molecules such as `NO_(2)` (V shaped), `NH_(3)` (pyramidal), `POCl_(3)` (tetahedral), `CH_(3)Cl` (tetrahedral), `SO_(2)` (angular), `H_(2)Se` (V shaped), `BrF_(5)` (square pyramidal), `XeF_(6)` (distorted octahedral), `O_(3)` (V - shaped) possess dipole moment.
