In diborane, each boron atom uses

A)  \[s{{p}^{2}}\]-hybrid orbitals for bonding

B)  p-orbitals for bonding

C)  \[s{{p}^{3}}\]-hybrid orbitals for bonding

D)  \[ds{{p}^{2}}\] hybrid for bonding

Correct Answer: A

Solution :

                 In diborane, boron atom is \[s{{p}^{2}}\]-hybridised with bond angle of \[{{120}^{o}}\] and having triangular planar structure.                 They form \[\sigma \]-bonds with H-atom by \[(s{{p}^{2}}-s)\] overlapping.
