pls explain the structure of diborane(b2h6).does hydrogen bonding work here?? but hydrogen bonding is only possible for highly electronegative elements(O,N,F).

Diborane (B2H6) has D2h structure with conventional covalent bond structure. It has four terminal and two bridged hydrogen atoms.

Bonds between boron and terminal hydrogen are 2-electron covalent bonds.

The bond between boron and hydrogen are held together by four electrons (each boron has 1 valence electron from 1 from hydrogen) forms 3-centre-2-electron bonding. It is also called banana bond.

The bond length of B-H(bridge) and B-H(terminal) is 1.22 A and 1.19 A. The B-H(bridge) bond is weaker compared to B-H(terminal).

Hydrogen bonding is different in diborane and the normal hydrogen bonding does not work out here.
