It is a strong Lewis base
It sublimes at $180\,^oC$ under vacuum
Both $(A)$ and $(C)$
In the electrolytic extraction of aluminium, cryolite is used
Colour of the bead in borax bead test is mainly due to the formation of
$BF_3$ on hydrolysis forms
If $B-Cl$ bond has a dipole moment, explain why $BCl_3$ molecule has zero dipole moment.
How would you explain the lower atomic radius of $Ga$ as compared to $Al$?
