The number of molecule(s) or ion(s) from the following having non-planar structure is______. NO 3 - , H 2 O 2 , BF 3 , PCl 3 , XeF 4 , SF 4 , XeO 3 , PH 4 + , SO 3 , Al OH 4 -

Step-by-step solution

The species which have sp 2 hybridisation with no lone pairs, sp 3 d 2 hybridisation with two lone pairs are planar molecules. The number of hybrid orbitals can be calculated as follows, No.of hybrid orbitals = 1/2(V+M-C+A) V = number of valence electrons M = number of monovalent atoms attached to central atom. C = Number of positive charges on the molecule A = Number of negative charges on the molecule SO 3 sp 2 Planar BF 3 sp 2 Planar NO 3 - sp 2 Planar SF 4 sp 3 d Non-Planar H 2 O 2 sp 3 Non-Planar PCl 3 sp 3 No
