More question practice

Aromatic explanationsPractise benzene stability, nitration equations and substitution explanations. OCR A also includes phenol. This set does not assess mechanism drawings. Open Polymer formulaeUse atom counts and condensed formulae to practise addition polymers, repeat-unit masses and polyester hydrolysis. Choose Year 12 for addition polymers only. Open Ester and acyl equationsRead explicit condensed formulae, name esters and write preparation and hydrolysis equations. Keep the carbon chain and acid/base form of each product correct. Open
