Question

(i) Number of P-P bonds in P₄S₃ is (A).

(ii) Amongs the following number of planar species is (B). 

XeF₂ , ClF₃ , H₂O, [XeF₅]^- , I₃^- , BCl₃ , XeF₄ , SF₄ , PCl₅ , SF₆ , IF₇ .

Determine the value of (A + B).

Answer 1

(i) 3

(ii) 7.

Planar molecules : 

XeF₂ , ClF₃ , H₂O, [XeF₅]^-, I₃ , BCl₃ , XeF₄ . SF₄ - See - Saw shape

PCl₅ - Trigonal bipyramidal SF₆ - Square bipyramidal IF₇ - Pentagonal bipyramidal
