JEE Mains · Chemistry · STD 12 - 7. Alcohol, phenol and ethers
Which one of the following substituents at para position is most effective in stabilizing the phenoxide ion ?
- A \(- CH_3\)
- B \(- OCH_3\)
- C \(- COCH_3\)
- D \(- CH_2OH\)
Answer & Solution
Correct Answer
(C) \(- COCH_3\)
Step-by-step Solution
Detailed explanation
Electron with drawing group stabilises the benzene ring due to delocalisation of charge. \(-CH_3\) and \(-CH_2OH\) are electron donating group and hence decrease the stability of benzene ring \(-OCH_3\) is weaker electron with drawing group than \(-COCH_3\) . Hence \(-COCH_3\)…
