Question

Can you explain sp^3 hybridisation with example CH4?

Answer 1

Carbon as a 4 A group has four electrons in its valance shell.It needs more 4 electrons for stability.So carbon electron configurations is 1s2,2s,2p2
In exited state the configuration is 1s2,2s1,2p3.So the orbitals intermix and form four hybrid orbitals of equal energy.These 4 orbitals overlap with each hydrogen atom and form sigma s-sp3 hybridization and angle between each atom is 109 degrees 28 minutes.
