Question

which of the following molecule has two types of X-F bond length (X=S,Xe, C, P) the options are A) PF5 B) SF6 C) XeF4 D) CF4 PLS ANSWER THIS

Answer 1

Hi Sandy, I am from Aakash too...

anyways, others say that c) is the correct option.

PS. I know what you are up to...

Answer: C

Answer 2

Phosphorus Penta-fluoride has two types of P-F Bond length.

First of all , refer to the attached diagram in order to understand the structure of Phosphorus Penta-fluoride.

• We can see that there are three P-F bonds present in the plane.

• And there are two P-F bonds present perpendicular to the plane.

The axial P-F bonds present perpendicular to the plane have higher Bond length as compared to those present in the equatorial plane.

• This is because , the axial bonds have lesser s orbital character and hence lesser orbital overlap.
