The true statements from the following are
1.

\mathrm{P}{\mathrm{H}_5}

and

\mathrm{BiC}{\mathrm{l}_5}

do not exist
2.

p\pi - d\pi

bond is present in

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

3.Electrons travel at the speed of light
4.

\mathrm{Se}{\mathrm{F}_4}

and

\mathrm{C}{\mathrm{H}_4}

have same shape
5.

\mathrm{I}_3^ +

has bent geometry

View answer and explanation

Correct option: B

1,2,5

Option B (1,2,5) is correct because

PH_5

and

BiCl_5

do not exist due to the inert pair effect and the inability of P to expand its octet,

SO_2

has

p\pi - d\pi

bonding, and

I_3^+

has a bent geometry.
