Question

Name the product which is obtained on oxidation of sodium borohydride by iodine

Answer 1

Oxidation of Sodium borohydride:

1. The inorganic chemical sodium borohydride, commonly known as Sodium tetra hydridoborate or Sodium tetrahydroborate has the formula${\mathrm{NaBH}}_4$. This solid white powder acts as a reducing agent.
2. Diborane was created by reacting a metal hydride with Iodine. In industrial manufacturing of diborane, this method is used frequently.$\underset{\mathrm{Sodium}\mathrm{borohydride}}{2{\mathrm{NaBH}}_4\left(\mathrm{s}\right)}+\underset{\mathrm{Iodine}}{{\mathrm{I}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Sodium}\mathrm{iodide}}{2\mathrm{NaI}\left(\mathrm{s}\right)}+\underset{\mathrm{Diborane}}{{\mathrm{B}}_2{\mathrm{H}}_6\left(\mathrm{g}\right)}+\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}$
3. The chemical compound diborane has the formula ${\mathrm{B}}_2{\mathrm{H}}_6$and is made up of boron and hydrogen.
4. It is a poisonous, flammable, colorless, pyrophoric gas with a sweet odor.

Therefore, Diborane is obtained on oxidation of sodium borohydride by iodine.
