Vedclass · Answer

(B) The hybridization of the central atom can be determined using the formula: $	ext{Steric Number} = (	ext{Number of bonded atoms}) + (	ext{Number of lone pairs})$.For $BeF_2$: $	ext{Steric Number} = 2 + 0 = 2$ ($sp$ hybridization).For $BCl_3$: $	ext{Steric Number} = 3 + 0 = 3$ ($sp^2$ hybridization).For $C_2H_2$: The carbon atoms have a steric number of $2$ ($sp$ hybridization).For $NH_3$: $	ext{Steric Number} = 3 + 1 = 4$ ($sp^3$ hybridization).Thus,the molecule with $sp^2$ hybridization is $BCl_3$.

Which of the following molecules has a central atom that adopts $sp^2$ hybridization?
