Statement $I :$ The nucleophilic addition of sodium hydrogen sulphite to an aldehyde or a ketone involves proton transfer to form a stable ion.
Statement $II :$ The nucleophilic addition of hydrogen cyanide to an aldehyde or a ketone yields amine as final product.
In the light of the above statements, choose the most appropriate answer from the options given below :
$\mathrm{A}+\mathrm{B} \rightleftharpoons 2 \mathrm{C}$
the value of equilibrium constant is $100$ at $298\, \mathrm{~K}$. If the initial concentration of all the three species is $1\, \mathrm{M}$ each, then the equilibrium concentration of $\mathrm{C}$ is $\mathrm{X} \times 10^{-1} \,\mathrm{M}$. The value of $\mathrm{x}$ is $.....$ (Nearest integer)
