How does diborane react with
a) H₂O b) CO c) NH₃ d) N(CH₃)₃

a) Reacts with H₂O : Diborane readily reacts with H₂O to give boric Acid.
${\mathrm{B}}_2{\mathrm{H}}_6+6{\mathrm{H}}_2\mathrm{O}\stackrel{ }{\to }\underset{(\mathrm{ortho} \mathrm{boric} \mathrm{acid})}{2{\mathrm{H}}_3{\mathrm{BO}}_3}+6{\mathrm{H}}_2$
b) Reacts with CO : Diborane reacts with CO and forms borane carbonyl adduct.
${\mathrm{B}}_2{\mathrm{H}}_6+2\mathrm{CO}\underset{2\mathrm{atm}}{\overset{1000°\mathrm{C}}{\to }}2{\mathrm{BH}}_3\cdot \mathrm{CO}$
c) Reacts with NMe₃ : Diborane reacts with trimethyl amine and forms an adduct.
${\mathrm{B}}_2{\mathrm{H}}_6+2\mathrm{N}{\left({\mathrm{CH}}_3\right)}_3\stackrel{ }{\to }2{\mathrm{BH}}_3\cdot \mathrm{N}{\left({\mathrm{CH}}_3\right)}_3$
d) Reacts with NH₃ : Diborane reacts with ammonia and forms diammoniate of diborane aduct which further heating gives borazine.
${\mathrm{B}}_2{\mathrm{H}}_6+2{\mathrm{NH}}_3\stackrel{{120}^{\circ }\mathrm{C}}{\to }{\mathrm{B}}_2{\mathrm{H}}_6\cdot 2{\mathrm{NH}}_3$
Diammoniate of diborane
$3{\mathrm{B}}_2{\mathrm{H}}_{6}2{\mathrm{NH}}_3\underset{200°\mathrm{C}}{\overset{∆}{\to }}\underset{\text{ (Borazole) }}{2{\mathrm{B}}_3{\mathrm{N}}_3{\mathrm{H}}_6}+12{\mathrm{H}}_2$
