Question: Explain the structure and bonding of diborane?
Diborane (B2H6) has a unique structure and bonding. It consists of two boron atoms and six hydrogen atoms arranged in a planar, triangular shape, with two hydrogen atoms above and below the boron plane. The bonding in diborane involves both covalent and dative (coordinate) bonds. Each boron atom has two half-filled 2p orbitals, which overlap with the half-filled 1s orbitals of two hydrogen atoms to form four normal covalent bonds. The remaining two hydrogen atoms are attached to the boron atoms through dative bonds, in which the lone pair of electrons on each hydrogen atom is shared with an empty 2p orbital on the adjacent boron atom. The result is a highly reactive and unstable molecule that readily reacts with other compounds.
