Consider the following sequence of reactions to give the major product (X) P g of the major product $\displaystyle (\mathrm{X})$ formed is reacted with $\displaystyle \mathrm{NaHCO}_3$ solution to liberate a gas which occupied $\displaystyle 11.2 \mathrm{dm}^3$ at STP. P = $\displaystyle \_\_\_\_$g. (Given molar mass in $\displaystyle \mathrm{g} \mathrm{mol}^{-1} \mathrm{H}: 1, \mathrm{C}: 12, \mathrm{O}: 16, \mathrm{Cl}: 35.5$ )
