COMEDK · Chemistry · 26. Alcohols Phenols and Ethers
Two statements, One Assertion [A ] and the other Reason [ R ] are given. Identify the correct option Assertion [A]: The decreasing order of the acidic character of the following is \(\mathrm{B}>\mathrm{D}>\mathrm{A}>\mathrm{C}\)
Reason \([\mathrm{R}]\) : Fluorine has larger -I effect than Cl and Br .
- A A is wrong but R is correct.
- B \(A\) is correct but \(R\) is wrong.
- C Both A and R are correct but R is not the correct explanation of A .
- D Both \(A\) and \(R\) are correct and \(R\) is the correct explanation of \(A\).
Answer & Solution
Correct Answer
(C) Both A and R are correct but R is not the correct explanation of A .
Step-by-step Solution
Detailed explanation
The acidity of substituted cyclohexanols is determined by the inductive effect (-I effect) of the substituent. The -I effect increases the acidity of the hydroxyl group by stabilizing the conjugate base (alkoxide ion) through electron withdrawal. The strength of the -I effect…
