Which are true statements among the following?(1)

\mathrm{P}{\mathrm{H}_5}\mathrm{ and BiC}{\mathrm{l}_5}

does not exist (2)

p\pi - d\pi

bonds are present in

\mathrm{S}{\mathrm{O}_2}

(3) Electrons travel with speed of light (4)

\mathrm{Se}{\mathrm{F}_4}\,\mathrm{and C}{\mathrm{H}_4}

has same shape (5)

\mathrm{I}_3^ +

has bent geometry

View answer and explanation

Correct option: B

1,\mathrm{ }2,\mathrm{ }5

Option B is correct.

PH_5

and

BiCl_5

do not exist due to the inability of P and Bi to form 5 bonds.

SO_2

has

p\pi - d\pi

bonds.

I_3^+

has a bent geometry.
