Question

All of the following undergo hybridization except A. C B. Si C. Mg D. B

Answer 1

Answer:

C: Mg

Explanation:

Hybridization of atomic orbitals is a fundamental concept introduced by Pauling that describes the mixing of orbitals at an atom which adds a definite direction to the Lewis - shared electron pair or electron chemical - bond concept.

Carbon(C) can hybridized on sp, sp2 and sp3 simply because it's valence shell gives room for it.

For silicon(si), when forming covalent bonds with other atoms, it's 3s and 3p orbitals are mixed with each other to form new hybrid orbitals.

Magnesium in itself doesn't hybridized except in magnesium hydrides.

Boron orbitals(B): when boron forms bonds with three other atoms like borazine, they are hybridized to either the sp2 or hybridized to the sp3 which occurs when boron forms bonds with four atoms just as is in metal borohydrides.
