Question

According to valence bond theory, which atomic orbitals of carbon may be hybridized to account for bonding? Why?

1s, 2s, and 2p orbitals all may hybridize; these orbitals are of the same phase.

Only 2p orbitals may hybridize; the 2p orbital is carbon’s highest-energy atomic orbital.

Only 1s and 2s orbitals of carbon may hybridize; each contains electrons to share in bonding.

Only 2s and 2p may hybridize; these orbitals contain valence electrons used in bonding.

Only 2s orbitals may hybridize; these orbitals contain valence electrons.
