Compound $\displaystyle (\mathrm{X})$ is subjected to the sequence of reactions as shown above. Molar mass of the major product $\displaystyle (\mathrm{Y})$ formed is $\displaystyle \_\_\_\_$ $\displaystyle \mathrm{g} \mathrm{mol}^{-1}$. (Given molar mass in $\displaystyle \mathrm{g} \mathrm{mol}^{-1} \mathrm{C}: 12, \mathrm{H}: 1, \mathrm{O}: 16$ )
