Vedclass · Answer

(A) In $S_N^1$ reactions,the rate depends on the stability of the carbocation intermediate. For the cyclic ethers in option $A$,the carbocation formed at the $3$-position in $3-$chloro$-3-$methyltetrahydropyran is tertiary and stabilized by the adjacent oxygen atom's lone pair (resonance),making it the most reactive. The order given in option $A$ is incorrect because $3-$chloro$-3-$methyltetrahydropyran should be the most reactive.For $E_1$ reactions,the rate depends on the stability of the carbocation intermediate,which follows the order: $3^\circ > 2^\circ > 1^\circ$. Thus,(tert-butyl chloride) > (isopropyl chloride) > (ethyl chloride) is correct.For $E_2$ reactions,the rate depends on the stability of the alkene formed and the number of $\beta$-hydrogens. The order (tert-butyl chloride) > (isopropyl chloride) > (ethyl chloride) is correct.For $S_N^1$ reactions of simple alkyl halides,the order is $3^\circ > 2^\circ > 1^\circ$,so (tert-butyl chloride) > (isopropyl chloride) > (ethyl chloride) is correct.
