Question

Identify the ortho and para directing groups towards aromatic electrophilic substitution reactions from the following list: -OH, -CN, COOH, -OCH3, -NHCOCH3, -CHO

• A. I, IV, V
• B. II, III, VI
• C. I, II, IV
• D. IV, V, VI

Hint:

Remember: Electron-donating groups activate the ring and direct to ortho/para positions in EAS.

Answer 1

The Correct Option is A

Ortho/para directors are typically electron-donating groups (EDGs).
- -OH (I), -OCH3} (IV), and -NHCOCH3} (V) are EDGs, thus ortho/para directors.
- -CN, -COOH, and -CHO are electron-withdrawing and meta directing groups.
