Directions : In this question, A statement of Assertion (A) is followe...
Assertion: With HI, anisole gives iodobenzene and methyl alcohol.
Reason: Iodide ions combine with smaller groups to avoid steric hindrance.
Explanation:
To understand the given assertion and reason, let's first discuss the reaction between anisole (methoxybenzene) and HI (hydrogen iodide).
The reaction between anisole and HI proceeds as follows:
Anisole + HI → Iodobenzene + Methanol
Now, let's examine the given assertion and reason individually:
Assertion: With HI, anisole gives iodobenzene and methyl alcohol.
This assertion is correct. When anisole reacts with HI, it undergoes a nucleophilic substitution reaction where the methoxy group (-OCH3) of anisole is replaced by an iodine atom (-I), resulting in the formation of iodobenzene. Simultaneously, a methyl alcohol molecule is formed as a byproduct.
Reason: Iodide ions combine with smaller groups to avoid steric hindrance.
This reason is incorrect. Steric hindrance refers to the repulsion between atoms or groups in a molecule that affects the reaction rate or outcome. In the given reaction, the size of the group (-OCH3) is not the determining factor for the substitution of iodide ions. The reaction occurs due to the nucleophilic nature of iodide ions, which readily attack the electron-deficient carbon of the methoxy group, resulting in the substitution. Steric hindrance is not a significant factor in this reaction.
Conclusion:
Based on the above analysis, we can conclude that the assertion is correct, but the reason is incorrect. Therefore, the correct answer is option 'c' - "If the Assertion is correct but Reason is incorrect."
