Answer: sp3.
- A sp3
- B sp2
- C sp
- D sp3d
Correct answer: A. sp3
Explanation: Nitrogen in NH3 is sp3 hybridised: three bonds and one lone pair in sp3 orbitals.
VSEPR theory predicts molecular shape from the number of bonding and lone electron pairs around the central atom.
Concept context
Understand how atoms join to form molecules. Covers ionic and covalent bonding, VSEPR theory, hybridization (sp, sp², sp³), molecular orbital theory, bond polarity, and intermolecular forces like hydrogen bonding.
