  1. 6.6 Aldehydes and Ketones 6.6.1 Aldehyde Structures LO: I understand the structure and nomenclature of aldehydes.

  2. H H O H C C C H H H carbonyl An alkanal (aldehyde) has a group at the end of the carbon chain. Alkanals have the the functional group: -CHO or Example: CH3CH2CHO propanal LO: I understand the structure and nomenclature of alkanals.

  3. 6.6.2 Alkanone Structures LO: I understand the structure and nomenclature of alkanones.

  4. An alkanone (ketone) has a carbonyl group within the carbon chain. Alkanones have the the functional group: or -COC- Example: CH3CH2COCH2CH2CH3 hexan-3-one LO: I understand the structure and nomenclature of alkanones.

  5. 6.6.3 Distinguishing Tests LO: I know how to distinguish between alkanals and alkanones chemically.

  6. orange green blue orange colourless silver Two carbonyl compounds, X and Y, are reacted with oxidising agents. From the results, compound X is an and compound Y is an . no reaction no reaction no reaction alkanal alkanone LO: I know how to distinguish between alkanals and alkanones chemically.
