- C and
- D and
Step-by-Step Verified Solution
The hybridisation of the central atom can be calculated as
H = 1 2 [ ( N o . o f e l e c t r o n s i n v a l e n c e s h e l l o f a t o m ) + ( N o . o f m o n o v a l e n t a t o m s a r o u n d c e n t r a l a t o m ) _ ( C h arge o n c a t i o n ) + ( C h arge o n a n i o n ) ]
_ For BF 3 , H = 1 2 [ ( 3 ) + ( 3 ) _ ( 0 ) + ( 0 ) ] _ 3 _ sp 2 hybridisation
_ For NO 2 - , H = 1 2 [ ( 5 ) + ( 0 ) _ ( 0 ) + ( 1 ) ] _ 3 _ sp 2 hybridisation
