Which of the following groups operates as an ortho and para directing group in electrophilic aromatic substitution reactions despite having a slight -I effect?
Options
- APhenolic (-OH) group
- BAmino (-NH2) group
- CMethyl (-CH3) group
- DCyano (-CN) group
Correct answer
A. Phenolic (-OH) group
Step-by-step solution
The phenolic (-OH) group is an ortho and para directing group in electrophilic aromatic substitution reactions. It does have a slight -I effect, but the resonance effect dominates, increasing electron density at the ortho and para positions.
