Explain the structure of diborane.

An aqueous solution of borax is basic.

What is the formula of colemanite?

An unknown inorganic compound $\text{'}\mathrm{A}\text{'}$ on reduction with ${\mathrm{LiAlH}}_4$ produced a hydride product $\text{'}\mathrm{B}\text{'}$ (along with other by-products). The product $\text{'}\mathrm{B}\text{'}$ contains $21.72\%$ of hydrogen in it. The product $\text{'}\mathrm{B}\text{'}$ on exposure to air gave boron trioxide. The compounds $\text{'}\mathrm{A}\text{'}$ and $\text{'}\mathrm{B}\text{'}$ are:

Borax reacts with concentrated $\mathrm{HCl}$ to produce a boron containing compound $\mathrm{X}$. Heating $\mathrm{X}$ with ${\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}$ converts it into $\mathrm{Y}$, which gives green edged flame. Identify $\mathrm{X}$ and $\mathrm{Y}$.

${\mathrm{B}}_2{\mathrm{H}}_6$ can't be prepared by :-
