A] ${\mathrm{H}}_3\mathrm{B}{\mathrm{O}}_3$ is a weak monobasic Lewis acid.
${\mathrm{H}}_3\mathrm{B}{\mathrm{O}}_3+\mathrm{H}-\mathrm{O}\mathrm{H}\rightleftharpoons \mathrm{B}{\left(\mathrm{O}\mathrm{H}\right)}_4^{-}+{\mathrm{H}}^{+}\dots ..\left(\mathrm{i}\right)$
B] Equilibrium (i) is shifted in forward direction by the addition of syn-diols like ethylene glycol which forms a stable complex with $\mathrm{B}{\left(\mathrm{O}\mathrm{H}\right)}_4^{-}$ .


C] It has a planar sheet like structure due to hydrogen bonding.
D] ${\mathrm{H}}_3\mathrm{B}{\mathrm{O}}_3$ is a weak electrolyte in water.
