Expert Answer:

Structure of B2H6:

  • The compound contains two hydrogen bridges in which four electrons are present, one electron from each boron atom and one electron from each hydrogen atom.
  • Each of these bridges contains a B-H-B bond of two electrons, one from on B-atom and one from H-atom.
  • These bonds are also called banana bond.
  • Each boron atom which is sp2 hybridised is also attached with two H-atoms by covalent bond in such a way so that both B-atoms which are not attached with each other and all the four covalently bonded H-atoms lie in one plane.
  • Out of two bridges bonds, each bond is placed above and below in a plane perpendicular to the plane of boron and terminal hydrogen atoms.
