Topics Tested
16. Hydroxy compounds
16.1. Alcohols

(a) classify alcohols as primary, secondary and tertiary alcohols, to include examples with more than one alcohol group (b) state characteristic distinguishing reactions, e.g. mild oxidation with acidified \( K_2Cr_2O_7 \) colour change from orange to green

17. Carbonyl compounds
17.1. Aldehydes and ketones

recall the reactions (reagents and conditions) by which aldehydes and ketones can be produced: (a) the oxidation of primary alcohols using acidified \( K_2Cr_2O_7 \) or acidified \( KMnO_4 \) and distillation to produce aldehydes (b) the oxidation of secondary alcohols using acidified \( K_2Cr_2O_7 \) or acidified \( KMnO_4 \) and distillation to produce ketones
