$\displaystyle \mathrm{R}_{\mathrm{f}}$ value for $\displaystyle 2$-methylpropene in a solvent system (Ethyl acetate + ether) is $\displaystyle 0.42$ . $\displaystyle 2$-methylpropene is treated with dilute $\displaystyle \mathrm{H}_2 \mathrm{SO}_4$ to give major organic product (X). $\displaystyle \mathrm{R}_{\mathrm{f}}$ value for (X) in the same solvent system under identical condition will be:
