AIIMS 2017 Chemistry Electrophilic Substitution Reactions Assertion Reason Question
In the following questions a statement of Assertion (A) followed by a statement of Reason (R) is given. Choose the correct answer out of the following choice.
Assertion (A) Nitration of salicylic acid gives picric acid by elimination of group.
Reason (R) OH group is strongly activating group hence, SE reaction takes place at o- and p-positions
Both the statements are true and Reason is the correct explanation of Assertion.
Both the statements are true but Reason is not the correct explanation of Assertion.
Assertion is true but Reason is false.
Both the statements are false.
Correct Answer
Detailed Explanation
Option A is correct because both statements accurately describe the nitration of salicylic acid. The hydroxyl (-OH) group is indeed a strong activating group, facilitating electrophilic substitution at the ortho and para positions, leading to the formation of picric acid through the elimination of the carboxyl (-COOH) group. Other options are incorrect as they either misrepresent the truth of the statements or fail to connect the reason as a valid explanation for the assertion. Understanding the role of activating groups in electrophilic aromatic substitution is crucial for predicting product formation in organic reactions.
