The options in this question are sp3, sp3d and sp2
Answer:
sp3d
Step-by-step explanation:
The hybridization scheme in a molecule determines the number of bonds the central atom can form with other atoms.
sp3 hybridization leads to the formation of four bonds by the central atom
sp2 hybridization leads to the formation of three bonds by the central atom
sp3d hybridization leads to the formation of five bonds by the central atom. Hence the answer.
