Answer 1

hyy mate ✌️

Diborane is an electron deficient molecule. The two boron atoms and the four terminal hydrogen atoms of the molecule are all in the same plane. These four terminal B -H bonds are regular 2-centered- 2 electron bonds. The bridging hydrogen atoms lie above and below this plane. ... Diborane is an electron deficient molecule.

Answer 2

Answer:

Diborane

B2H6 is an electron-deficient compound. B2H6 has only 12 electrons – 6 e– from 6 H atoms and 3 e– each from 2 B atoms. Thus, after combining with 3 H atoms, none of the boron atoms has any electrons left.

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 (B–H–B) bonds are three-centre two-electron (3c – 2e–) bonds.
