Solution:
(a) Diborane
is a compound that does not have an electron. just has 12 electrons 
of 
molecules and 
of 
iotas each. So none of the boron molecules has any electrons left subsequent to being blended in with 
particles. 
-beam diffraction studies showed the diborane structure as:
Two boron and four-terminal molecules of hydrogen 
lie one way, while the other two connecting particles of hydrogen 
are in the surface opposite to the plane of boron iotas. Once, of the two molecules of hydrogen spanning, one particle of 
lies over the plane, and the other beneath the plane. The terminal bonds are standard twocentre two-electron 
bonds, while the two bridgings 
bonds are three-focus two-electron (3c 
bonds.

(b) Boric corrosive
Boric corrosive is organized in a layered structure. Each planar unit 
is associated by molecules to one another. The molecules structure a covalent bond with a unit while another unit frames a hydrogen bond. The dabbed lines, in the given figure, address hydrogen bonds.
