Which pair of groups contains both ortho and para directing groups?
Correct answer: A. -OH, -RCO
- A. -OH, -RCO
- B. -NR3, -CN
- C. -OCH3, -CHO
- D. -N(CH3)2, -NH2
Explanation
Both -OH and -RCO (carbonyl group) are ortho-para directing groups in electrophilic aromatic substitution reactions

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.

Chlorination of toluene in the presence of sunlight produces:Sunlight provides the energy to break a chlorine molecule (Cl₂) into chlorine radicals (Cl∙).These radicals then react with the toluene molecule, primarily targeting the benzylic position (the carbon atom next to the benzene ring) due to its stability.This reaction leads to the substitution of a hydrogen atom on the benzylic carbon with a chlorine atom, forming benzyl chloride.
