$B_3N_3$
$SiC$

The gaseous product $(s)$ expected at room temperature by reaction of sodium borohydride and boron trifluoride under anhydrous conditions is/are:
Write reactions to justify amphoteric nature of aluminium.
The structure of aluminium bromide is best represented as :
The formation of molecular complex $BF_3 - NH_3$ results in a change in hybridization of boron
$(i)\,Al\,\xrightarrow{{{N_2}}}\,A$ $(ii)\,Al\,\xrightarrow{c}\,B$
Here $A$ and $B$ on hydrolysis respectively gives
