Chemistry - CHEMICAL BONDING Question with Solution | TestHub

It acts as a lewis acid by accepting eletrons from a hydrogen ion and it turn releases${\mathrm{H}}^{+}$ions
$\mathrm{T}{\mathcal{l}}^{+3}$acts as on oxidizing agent$\mathrm{A}{\mathcal{l}}^{+3}$acts as reducing agent because the stability of lower oxidation state on moving down the group in increases due to pair effect stability$\mathrm{T}{\mathcal{l}}^{+3}$pair effect stability$\mathrm{T}{\mathcal{l}}^{+1}>\mathrm{T}{\mathcal{l}}^{+3}$
Hydrogen bonding in  H 3 B O 3  gives it a layered structure.
$\mathrm{B}(\mathrm{O}\mathrm{E}\mathrm{t}{)}_3$imparts green colour to the burner flame.
