A summary of aromatic compounds (benzene) in Module 6 of OCR Chemistry A-Level. It contains diagrams on how to do the mechanisms, regenerations of the catalyst and forming the electrophile and more. It follows the OCR specification on everything you need to know for benzene and is written as exam-style answers.

answers for aldehydes and ketones which can be used as a summary, including the mechanism for nucleophilic addition, tollen's reagent, oxidation or resistance to oxidation depedning on the type of organic compounds.

research skills on PAG 12 investigating iron tablets, providing ideas on the structure of the plan and what to search for exactly. to be made not for copying but for ideas on sentence starters. includes role of iron in the blood, types of iron tablets, method for titration, risk assessment and apparatus.

Bond enthalpy, enthalpy changes etc. Following the spec, just has the key points you need to know for the exam. Helped me to achieve an A* in my exam and I hope it can do the same for you!!! - Best way to use these is to read them and then do a question booklet on the topic straight after - if you need any help Im not sure if there is a way to contact me through this but Im glad to help! topics include: 1. enthalpy changes 2. measuring enthalpy changes enthalpies 4. hess' law and ent...
