Write preparation of diborane and give physical and chemical properties of it.
The green colour produced in the borax bead test of a chromium$(III)$ salt is due to formation of______:
In $B_2H_6$
Draw structure of $Al_2Cl_6$ and give uses of $AlCl_3$.
When $BCl_3$, is treated with water, it hydrolyses and forms $[B(OH)_4]^-$ only whereas $AlCl_3$ in acidified aqueous solution forms $[Al(H_2O)_6]^{3+}$ ion. Explain what is the hybridizations of boron and aluminum in these species?
