Arrange the following compounds in increasing order of C – OH bond length
methanol, phenol, p-ethoxyphenol
Select the correct option:
A
phenol < p-ethoxyphenol < methanol
B
methanol < phenol < p-ethoxyphenol
C
methanol < p-ethoxyphenol < phenol
D
phenol < methanol < p-ethoxyphenol
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
C-OH bond length in methanol, phenol and p-ethoxyphenol 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.
correct increasing order is
phenol < p-ethoxyphenol < methanol
