Question

B4H10 molecule show s_bridge bond​

Answer 1

Answer:

Diborane is an electron deficient compound. In diborane, total number of valence electrons is 12. diborane contains two coplanar BH

groups. Diborane has four terminal hydrogen atoms and the two boron atoms lie in one plane. Above and below this plane, there are two bridge hydrogen atoms. The bridge hydrogen atoms are present in a plane perpendicular to rest of the molecule. Each bridge hydrogen is bonded to the two boron atoms only by sharing of two electrons. These are called three centred two electron (3c−2e) bonds, also known as banana or tau bonds. The terminal B−H bonds are 2c−2e bonds.
