Q. In two separate experiments equal quantities of an alkyl halide, $C_4H_9Cl$, were treated at the same temperature with equal volume of $0.1\, molar$ and $0.2\, molar$ solutions of $NaOH$ respectively. In the two experiments,$t_{1/2}$ of the two reactions were the same. The most likely structure of halide is
Haloalkanes and Haloarenes
Solution:
