methanol, phenol, p-ethoxyphenol
methanol, phenol, p-ethoxyphenol
Choose an option
Show full solutionCorrect option: D
Correct answer
Dphenol < p-ethoxyphenol < methanol
Step-by-step explanation
C-OH bond length in Among methanol, phenol and
p-ethoxyphenol, C-OH bond length is least in phenol due to
resonance and maximum in methanol due to
lack of resonance whereas it will have some
intermediate value in p-ethoxyphenol.
phenol < p-ethoxyphenol < methanol
phenol < p-ethoxyphenol < methanol
