Determine the type of hybridization present in the following molecules.

1. BF3 exhibits sp2 hybridization.
2. NO2 exhibits sp2 hybridization.
3. NH2 exhibits sp3 hybridization.
4. H2O exhibits sp3 hybridization.

Correct answer: BF3 exhibits sp2 hybridization.

Solution

In BF3, the boron atom forms three sigma bonds with fluorine atoms and has no lone pairs, leading to sp2 hybridization. The other options are also correct but the question asks for the hybridization in the given molecules, and option A is the first correct match.
