Question

on the basis of hybrid formation, explain the existence of compounds of column IVA such as CH4 when the elements of column IVA only have two unpaired electrons in normal state

Answer 1

CH4 compound is formed by sharing of electrons with hydrogen atom. They are bonded by ionic bonds. They undergo sp^3 hybridization.

Step-by-step explanation:

The group 4A elements have 4 electrons in their valence shell or highest energy orbitals ie 2s^2, 2p^2

They share electrons from other elements thereby stabilising their valence shell and form bonds between them. The bonds can be covalent or ionic. It undergoes sp^3 hybridization.

The four valence electrons of the carbon atom are distributed equally in the hybrid orbitals, and each electron of carbon pairs with an electron of hydrogen atom when the C–H bonds form.
