The structure of diborane contains:
A
Four $2C-2e$ bonds and two $3C-2e$ bonds
B
Two $2C-2e$ bonds and two $3C-2e$ bonds
C
Two $2C-2e$ bonds and two $3C-3e$ bonds
D
Four $2C-2e$ bonds and two $3C-3e$ bonds
Solution
This is the structure of $B _2 H _6$
Four hydrogen are connected to $B$ atoms by covalent bonds. So there are four $2$ centered$- 2$ electron bonds
$2$ hydrogen atoms are connected by bridge and it is connected to $2$ boron atoms . So, there are $3$ -centred-$2$- electron bonds
$( H – B ) \rightarrow 2\quad C -2 e$ bonds
$(B-H-B) \rightarrow 3\quad C-2e$ bonds
