AIIMS 2019 Chemistry Carbocation Stability MCQ Question
The stability of carbocation which is formed in the reaction decides the reactivity towards Sₙ1 reaction. Consider the order of reactivity as shown below, Since, the compound¹⁻chloro,¹⁻ethylcyclopentane is more reactive towards Sₙ1 mechanism than¹⁻chlorocyclopentane as it forms more stable tertiary carbocation as intermediate.
Correct Answer
Detailed Explanation
The stability of carbocations is crucial in determining the reactivity of compounds in Sₙ1 reactions. In this case, 1-chloro-1-ethylcyclopentane forms a more stable tertiary carbocation compared to 1-chlorocyclopentane, which leads to increased reactivity in the Sₙ1 mechanism. Other options are not applicable as they do not provide relevant information or alternatives regarding the stability of carbocations and their influence on reaction mechanisms. Understanding the relationship between carbocation stability and reactivity is essential for predicting the outcomes of nucleophilic substitution reactions.
