Revise:
Weak acids partially dissociate
Energy required to dissociate ethanoic acid
Why the enthalpy change is less exothermic
Heat loss causing experimental values to be less exothermic than data book values
This is useful because Edexcel often tests explanation after a calculation.

Butan-2-ol chemistry is useful synoptic practice because it links alcohols, alkenes, ketones, haloalkanes and amines.
Students should revise:
Dehydration of alcohols using concentrated sulfuric acid
Oxidation of secondary alcohols to ketones
Electrophilic addition of HBr to alkenes
Markovnikov’s rule
Carbocation stability
Distinguishing butan-2-ol and butanone
Two-step synthesis of 2-aminobutane
This is a strong predicted topic because it tests whether students can connect organic reactions into a route rather than memorising isolated facts.
