Answer: Carbonyl compounds.
- A Alkanes during normal conditions
- B Benzene as generally observed
- C Carbonyl compounds
- D Ethers in typical laboratory settings
Correct answer: C. Carbonyl compounds
Explanation: The electrophilic carbonyl carbon undergoes nucleophilic addition reactions.
Curved arrows show the nucleophile attacking the carbonyl carbon while the C=O pi electrons move onto oxygen, giving a tetrahedral alkoxide intermediate.
Concept context
Aldehydes, ketones, carboxylic acids, and their derivatives (esters, amides, acid chlorides). Key reactions include nucleophilic addition, Aldol condensation, Cannizzaro, and Claisen. Very heavily tested in JEE and NEET.
