Vedclass · Answer

(A) In diborane $(B_2H_6)$,each boron atom undergoes $sp^3$ hybridization.In the bridged structure of diborane,the $B-H-B$ angle is $83^{\circ}$,not $180^{\circ}$.Each boron atom is linked to two terminal hydrogen atoms via $2c-2e$ bonds and two bridged hydrogen atoms via $3c-2e$ bonds. Thus,statement $3$ is correct.Diborane has $8$ atoms ($2$ Boron and $6$ Hydrogen). Total valence electrons = $2 	imes 3 + 6 	imes 1 = 12$. These $12$ electrons are involved in bonding ($4$ terminal $B-H$ bonds and $2$ bridged $B-H-B$ bonds). Thus,statement $4$ is correct.Therefore,statements $1, 3,$ and $4$ are correct.

Consider the following statements for diborane $(B_2H_6)$:
$1.$ Boron is approximately $sp^3$ hybridized.
$2.$ $B-H-B$ angle is $180^{\circ}$.
$3.$ There are two terminal $B-H$ bonds for each boron atom.
$4.$ There are only $12$ bonding electrons available.
Which of these statements are correct?
