In how many of the following molecules, all atoms are in same plane? C l F 3 H 2 O P C l 3 B F 3 S F 4 H 2 S O C l 2 S O 3 X e F 6 N H 3 C 6 H 6 X e F 2 X e F 4 P C l 5 I 2 C l 6 P H 3

Step-by-step solution

Planar molecules C l F 3 , X e F 4 , H 2 O , H 2 S , O C l 2 , C 6 H 6 , I 2 C l 6 , B F 3 , S O 3 , X e F 2 C l F 3 → Central atom C l has 2 . l p + 3 B p = s p 3 d hybridised it is T-shape (planar) H 2 O → Central atom O - has 2 l p + 2 B p = s p 3 hybridised (angular)( planar) P C l 3 → Central atom P - has 1 l p + 3 p → s p 3 hybridised pyramidal (non planar) B F 3 → s p 2 hybridised → triagonal planar (planar) S F 4 → C e n t r a l a t o m S has 1 l p + 4 B p , s p 3 d hybridised see-saw structure (non planar)
