{NaBH}_{4}

with

{I}_{2}

(b) Each boron atom is in

{sp}^{2}

hybridized state
(c) Diborane has one bridged

3

centre-

2

-electron bond
(d) Diborane is a planar molecule

Quantrex Academy · Accepted Answer

Correct answer: B. (a) only

Diborane is prepared by the reaction of ${NaBH}_{4}$ with ${I}_{2} .$ $2{NaBH}_{4} + {I}_{2} \to {B}_{2}{H}_{6} + 2NaI + {H}_{2}$
In diborane, $B$ is ${sp}^{3}$ hybridized. It is non-planar molecule and it has two $3c - 2{e}^{-}$ bonds. Given below are the statements about diborane (a) Diborane is prepared by the oxidation of NaBH _ 4 with I _ 2 (b) Each
