Question

Identify the incorrect statement about \(PCl_5\). 

(1) \(PCl_5\) possesses two different Cl – P – Cl bond angles 

(2) All five P – Cl bonds are identical in length 

(3) \(PCl_5\) exhibits sp3d hybridisation 

(4) \(PCl_5\) consists of five P – Cl (sigma) bonds

Answer 1

Correct option is (2) All five P – Cl bonds are identical in length

It is \(sp^3d\) hybridised with axial to equatorial angle of \(90 ^\circ\) and equatorial bond angles of \(120^\circ\). It has five P – Cl sigma bonds. 

Axial bonds are longer than equatorial bonds.
