Questions and Answers

Which functional group distinguishes carboxylic acids from aldehydes and ketones?

  • Ester group
  • Phenyl group
  • Alkyl group
  • Carboxyl group (correct)
  • Which functional group is present in aldehydes, ketones, and carboxylic acids?

  • Amino group
  • Carbonyl group (correct)
  • Hydroxyl group
  • Alkene group
  • How do aldehydes, ketones, and carboxylic acids differ in terms of reactivity?

    Aldehydes are more reactive than ketones and carboxylic acids due to the presence of a hydrogen atom on the carbonyl group. Carboxylic acids are more acidic compared to aldehydes and ketones.

    What are the common methods for synthesizing aldehydes, ketones, and carboxylic acids?

    <p>Aldehydes can be synthesized by the oxidation of primary alcohols or the ozonolysis of alkenes. Ketones can be synthesized by the oxidation of secondary alcohols or the Friedel-Crafts acylation of aromatic compounds. Carboxylic acids can be synthesized by the oxidation of primary alcohols, aldehydes, or the hydrolysis of nitriles.</p> Signup and view all the answers
