Explain sp hybridisation with an example.

1.	Explain sp hybridisation with an example.
Answer» SOLUTION :`C_(1)H_(2)`-ethyne ofacetylene Electronic CONFIGURATION of C excited state `-1s^(2)2s^(2)2p^(3)` Valance orbital representation Sp hybridised, C contains 2 unpaired electron and one each in py and pz two sp hybridised C combines with two `1s^(1)` orbital of H. Two more hybrid orbitals each carbon with 1 s atomic orbitals ofhydrogen to FORM sigmabonds. The unhybrised 2pz orbitals of both the carbon atoms now overlap sideways to form carbon-carbon pi-bond.
