Question
Consider the compounds, $BCl_3$ and $CCl_4$. How will they behave with water? Justify.

Answer

$BCl_3$ is an electron deficient compound. Also, it has an empty unhybridised p-orbital which can accept electrons. In presence of water, $BCl_3$ hydrolyses and forms $B(OH)_3$.

But, when $CCl_4$ is mixed with water, no reaction takes place because carbon neither has any unhybridised, empty p-orbital where it can accommodate electrons from water nor it has empty d-orbital.
$CCl_4 + H_2O$ → No reaction.

When a mixture of ammonium chloride and potassium dichromate was heated, a stable colourless gas ‘A’ is evolved which did not support combustion, but Mg continued burning in it. The gas reacted with $CaC_2$ in electric furnace forming a solid 'B'. Which was slowly hydrolysed by water forming a insoluble substance 'C' and a solution of substance 'D' which turns red litmus blue and gives white fumes with conc HCl to form ‘E'. Identify A to E and write chemical reactions involved.
