4short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is the carbonyl group?Show answer
Aldehydes () and ketones () both contain the carbonyl group C=O. Oxygen is more electronegative than carbon, so the bond is polar: the carbon is slightly positive () and open to attack by nucleophiles. The characteristic reaction is nucleophilic addition.
What is q1?Show answer
State the reagent and observation for a test that confirms a compound contains a carbonyl group. [2 marks]
What is q2?Show answer
Name the product of reducing propanone with . [1 mark]
What is q3?Show answer
Explain why ethanal gives a silver mirror with Tollens' reagent but propanone does not. [2 marks]
