Haloalkanes And Haloarenes Question 7
Question 7 - 2024 (29 Jan Shift 1)
Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R :
Assertion A : Aryl halides cannot be prepared by replacement of hydroxyl group of phenol by halogen atom.
Reason R : Phenols react with halogen acids violently. In the light of the above statements, choose the most appropriate from the options given below:
(1) Both $\mathrm{A}$ and $\mathrm{R}$ are true but $\mathrm{R}$ is NOT the correct explanation of $\mathrm{A}$
(2) $A$ is false but $R$ is true
(3) $\mathrm{A}$ is true but $\mathrm{R}$ is false
(4) Both $\mathrm{A}$ and $\mathrm{R}$ are true and $\mathrm{R}$ is the correct explanation of $\mathrm{A}$
Show Answer
Answer (3)
Solution
Formula: Halogenation
Assertion (A): Given statement is correct because in phenol hydroxyl group cannot be replaced by halogen atom.
Reason $(\mathrm{R})$ :
Given reason is false
Hence Assertion (A) is correct but Reason (R) is false
