Question

explain the structure of diborane

Answer 1

Formula for diborane is B2H6 .It is colourless and highly unstable gas at room temperature.Its odour is sweet .It produces explosive mixture when get mixed with air which makes it dangerous.

Answer 2

In diborane four terminal B-H bonds are two centre - two electron bonds. Two bridge B ? H ? B bonds (or banana bonds) are three centre - two electron bonds.2 boron and 4 terminal hydrogen atoms (Ht) lie in one plane, while the other two bridging hydrogen atoms (Hb) lie in a plane perpendicular to the plane of boron atoms. Again, of the two bridging hydrogen atoms, one H atom lies above the plane and the other lies below the plane. The terminal bonds are regular two-centre two-electron (2c 2e) bonds, while the two bridging (BHB) bonds are three-centre two-electron (3c 2e) bonds.
