A
Both the Boron atoms are 
hybridised.
hybridised.
B
There are two 3 -centre-2-electron bonds.
C
The four terminal B-H bonds are two centre two electron bonds
D
The four terminal Hydrogen atoms and the two Boron atoms lie in one plane.
Text Solution
Verified by ExpertsThe correct answer is:
A
B is 
hybridized.
3 centre 2 electron bond which is called bridge bonding or banana bond. There are two different bonds that is 3 centre 2 electron and 2 centre 2 electron. So, bond lengths are different. Molecule is non-planar as 4 terminal hydrogen atoms and two boron atoms lie in one plane & rest two hydrogen lies in another plane.
