Question

Examples when filled orbitals of valence shell take part in hybridization

Answer 1

The atomic s- and p-orbitals in boron's outer shell mix to form three equivalent hybrid orbitals. These particular orbitals are called sp2 hybrids, meaning that this set of orbitals derives from one s- orbital and two p-orbitals of the free atom. The Lewis structure for ethene: The carbon atoms are sp2 hybridized.
