Vedclass · Answer

(A) The given reaction is an $E2$ elimination reaction involving a tertiary alkyl halide with a strong base $(C_2H_5O^-K^+)$ and heat $(\Delta)$.$1$. The substrate is $1$-chloro-$1$-ethyl-$2$-methylcyclohexane.$2$. Elimination can occur by removing a proton from the $\beta$-carbons:- Removing a proton from the ethyl group leads to the exocyclic double bond product $(A)$.- Removing a proton from the $C_2$ position (which has the methyl group) leads to the endocyclic double bond product $(C)$.- Removing a proton from the $C_6$ position leads to the endocyclic double bond product $(D)$.$3$. Product $(B)$ is not possible as it would require a double bond at a bridgehead position or an impossible geometry for this specific substrate structure.$4$. Among the possible products,$C$ is the most substituted (tetrasubstituted) and thus the most stable (Saytzeff product).$5$. However,$A, C,$ and $D$ are all possible elimination products depending on the kinetic and thermodynamic control of the reaction.$6$. Therefore,$A, C,$ and $D$ are the products.

Which of the following is/are the product$(s)$ of the given reaction?
$1$-chloro-$1$-ethyl-$2$-methylcyclohexane $\xrightarrow{C_2H_5O^-K^+ / \Delta}$ ?
