Equal amount of an alkyl halide $\left({\mathrm{C}}_4{\mathrm{H}}_9\mathrm{C}\mathrm{l}\right)$ is reacted at the same temperature with equal volume of $0.2 \mathrm{M}$ and $0.4 \mathrm{M}$ solution of $\mathrm{K}\mathrm{O}\mathrm{H},$ respectively, in two separate experiments. The time taken for the reaction of $50\%$ of $\left({\mathrm{C}}_4{\mathrm{H}}_9\mathrm{C}\mathrm{l}\right)$ was found to be same, the alkyl halide is
