$sp$-hybridisation

Vedclass · Answer

(A) The structure of acetylene is $HC \equiv CH$. In this molecule,each carbon atom is bonded to one hydrogen atom by a single bond and to the other carbon atom by a triple bond. Since each carbon atom is involved in one triple bond (one $\sigma$ and two $\pi$ bonds) and one single $\sigma$ bond,it has two $\sigma$ bonds and zero lone pairs. Therefore,the steric number is $2$,which corresponds to $sp$-hybridisation.
