NEETChemistryAlcohols Phenols and Ethers
Explain why p-nitrophenol is more acidic than phenol.
Options
- AThe presence of an electron-withdrawing group, the -NO 2 group,improves the acidic strength of p-nitrophenol b
- Bp-Nitrophenol has a higher molecular weight than phenol.
- Cp-Nitrophenol has a lower molecular weight than phenol.
- DThe presence of a nitro group in p-nitrophenol destabilizes the phenoxide ion formed during deprotonation.
Correct answer
A. The presence of an electron-withdrawing group, the -NO 2 group,improves the acidic strength of p-nitrophenol b
Step-by-step solution
Correct Option is : (A) The presence of an electron-withdrawing group, the -NO 2 group,improves the acidic strength of p-nitrophenol by stabilizing the phenoxide ion, hence para-nitrophenol is more acidic than phenol.
