QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Carbonyl Compounds and their Reactions.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

Describe one chemical test to distinguish between an aldehyde and a ketone.
Explain why aldehydes are more reactive than ketones towards nucleophilic addition reactions.
Explain why ketones do not give a positive Fehling's test.
Name the functional group present in ketones.
State the difference in the structure of an aldehyde and a ketone.
A student adds sodium bisulfite (NaHSO3) to a solution of an unknown carbonyl compound and observes the formation of a white crystalline solid. What does this indicate about the type of carbonyl compound present?
A solution of an unknown carbonyl compound is treated with 2,4-dinitrophenylhydrazine and a yellow precipitate forms. The compound is then tested with Fehling's solution, but no color change is observed. What type of compound is present?
