The species, having bond angles of $120^o $ is
$ClF_3$
$NCl_3$
$BCl_3$
$PH_3$
$AlCl_3$ on hydrolysis gives:
$B{\left( {OH} \right)_3} + NaOH \to NaB{O_2} + Na\left[ {B{{\left( {OH} \right)}_4}} \right] + {H_2}O$
How can this reaction is made to proceed in forward direction?
Aluminium trifluoride is insoluble in anhydrous $HF$ but dissolves on addition of $NaF$. Aluminium trifluoride precipitates out of the resulting solution when gaseous $BF $$_{3}$ is bubbled through. Give reasons.
The structure of diborane contains:
The liquefied metal which expands on solidification is
