JEE Mains · Chemistry · STD 12 - 7. Alcohol, phenol and ethers
Rate of dehydration of alcohols follows the order
- A \(2^o > 1^o >CH_3OH >3^o\)
- B \(3^o > 2^o > 1^o > CH_3OH\)
- C \(2^o> 3^o > 1^o > CH_3OH\)
- D \(CH_3OH > 1^o >2^o > 3^o\)
Answer & Solution
Correct Answer
(B) \(3^o > 2^o > 1^o > CH_3OH\)
Step-by-step Solution
Detailed explanation
The order of dehydration among three type of alcohols is \(3^o > 2^o > 1^o > CH_3OH\). This behaviour is related to the relative stabilities of carbocations \((3^o > 2^o > 1^o)\).
