$(i)\,Al\,\xrightarrow{{{N_2}}}\,A$ $(ii)\,Al\,\xrightarrow{c}\,B$
Here $A$ and $B$ on hydrolysis respectively gives
$NH_3, \,C_2H_2$
$NO,\, CH_4$
$NH_3,\,CH_4$
$NO,\,C_2H_2$
$AlCl_3$ on hydrolysis gives:
$BCl_3$, exists as monomer whereas $AlCl_3$ is dimerized through halogen bridging. Give reason. Explain the structure of the dimer of $AlCl_3$ also.
Borax is converted into crystalline boron by the following steps
${B{orax}}\xrightarrow{X}{H_3}B{O_3}\xrightarrow{\Delta }{B_2}{O_3}\xrightarrow[\Delta ]{Y}B$,
$X$ and $Y$ are respectively
