Why does boron trifluoride behave as a Lewis acid?
Give chemical properties of elements of group $-13$.
$B{X_3} + N{H_3}\xrightarrow{{R.T}}B{X_3}.N{H_3} + Heat\,of\,adduct\,formation\,\left( {\Delta H} \right)$ The numerical value of $\Delta H$ is found to be maximum for
Carbongene has $X\%$ of $CO_2$ and is used as an antidote for poisoning of $Y.$ Then, $X$ and $Y$ are
