Question

Consider the following statements ;

(I) Thehybridisation found in cation of solid PCl5 is sp3.

(II) In AB2L2 type the BAB bond angle is always greater than the normal tetrahedral bond angle.

(III) In ClO3–, NH3 and XeO3, the hybridisation and the number of lone pairs on the central atoms are same.

(IV) In P4 molecule, there are six P – P bonds and four lone pairs of electrons. of these statements :

• A. I, II and III are correct only
• B. I, III and IV are correct only
• C. III and IV are correct only
• D. All are correct

Answer 1

Answer: (B)

I, III and IV are correct only

Answer 2

(I) [PCl4]+ $\rightarrow$sp3

(II) has$\approx$102⁰ bond angle due to lp – lp repulsion, as bond pairs are closer to F-atoms.

(III) All have sp3 hybridisation and one lone pair.

(IV)
