Question

The Polar molecules are

• A.
• B.
• C. PCl₃F₂
• D. PCl₂F₃

Answer 1

Answer: (B), (D)

The correct options are
B
D

PCl₂F₃

Benzene is a symmetrical molecule and no net polarity.

Inorganic benzene is also called Borazine $\left(BH{)}_3\right(NH{)}_3$ Which is polar.

Compounds (3) and (4) have trigonal bipyramidal structure [Forom VSEPR]

From this symmetry, net dipole moment is zero ⇒ non - polar

${\mu }_{P-Cl}\ne {\mu }_{P-F}$

So, net dipole moment is non-zero $\Rightarrow$ polar molecular
