The ortho/para directing group among the following is
Correct answer: D. NHCOCH3
- A. COOH
- B. CN
- C. COCH3
- D. NHCOCH3
Explanation
The amide group (NHCOCH3) is an ortho/para directing group. This means that it will direct the incoming electrophile to the ortho and para positions on the aromatic ring. The other options (COOH, CN, COCH3) are meta directing groups and will direct the electrophile to the meta positions.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
