The Correct Option is A
Solution and Explanation
Explanation:
- BF3: The central atom, boron, forms three sigma bonds with fluorine and has no lone pairs. It undergoes sp2 hybridization.
- NO2−: The nitrogen atom has three regions of electron density (two sigma bonds and one lone pair). This corresponds to sp2 hybridization.
- H2O: The central atom, oxygen, has two sigma bonds and two lone pairs, corresponding to sp3 hybridization.
- NH2−: The nitrogen atom forms two sigma bonds and has two lone pairs, corresponding to sp3 hybridization.
Thus, only BF3 and NO2− exhibit sp2 hybridization.
Final Answer: Option (1).
