Aldehydes & Ketones MCQs with Answers

Welcome to the Aldehydes & Ketones MCQs with Answers, it helps learners quickly identify areas for improvement in Aldehydes & Ketones Online Test.

Aldehydes and ketones are important classes of organic compounds known for their distinct chemical properties and diverse applications across various industries. MCQs (Multiple Choice Questions) focusing on aldehydes and ketones help assess understanding of their structures, reactions, and roles in organic chemistry.

Aldehydes are characterized by the presence of a carbonyl group (C=O) bonded to at least one hydrogen atom. They exhibit unique reactivity due to the electrophilic nature of the carbonyl carbon, making them susceptible to nucleophilic attack and oxidation. MCQs on aldehydes typically cover topics such as their preparation methods, reactions (e.g., nucleophilic addition), and distinguishing tests (e.g., Tollens’ test).

Ketones, on the other hand, feature a carbonyl group bonded to two carbon atoms. They share some reactivity traits with aldehydes but differ in stability and selectivity in certain reactions. MCQs on ketones often explore their synthesis, reactions (e.g., nucleophilic substitution at the carbonyl carbon), and applications in pharmaceuticals, solvents, and flavoring agents.
