Vedclass · Answer

(B) $(i)$ $2NaBH_4 + I_2 ightarrow B_2H_6 + 2NaI + H_2$. This statement is correct.$(ii)$ $B_2H_6 + 3O_2 ightarrow B_2O_3 + 3H_2O + 	ext{Energy}$. This statement is correct as diborane is highly flammable.$(iii)$ $B_2H_6 + 6H_2O ightarrow 2B(OH)_3 + 6H_2$. $B(OH)_3$ (orthoboric acid) acts as a weak monobasic Lewis acid by accepting $OH^-$ from water: $B(OH)_3 + 2H_2O ightleftharpoons [B(OH)_4]^- + H_3O^+$. Thus,statement $iii$ is incorrect.

Identify the correct statements:
$i$. Oxidation of $NaBH_4$ with $I_2$ gives $B_2H_6$
$ii$. $B_2H_6$ burns in oxygen and releases an enormous amount of energy
$iii$. $B_2H_6$ on hydrolysis gives a tribasic acid
