Final answer:
The molecule that can be described in terms of sp3 hybrid orbitals of the central atom is NH3. In NH3, the nitrogen atom forms four sp3 hybrid orbitals, accommodating three single bonds and one lone pair of electrons.
Step-by-step explanation:
The molecule for which the bonding can be described in terms of sp³ hybrid orbitals of the central atom is NH3. In NH3, the nitrogen atom uses its 2s and 2p orbitals to form four sp³ hybrid orbitals, which accommodate three single bonds and one lone pair of electrons.
