AQA A Level Chemistry复习笔记7.9.1 Organic Mechanisms

Organic Mechanisms

• Throughout the A Level course you have met a number of organic mechanisms
  • You must be able to provide these in full if asked for
  • You must be able to apply your knowledge of what happens in a reaction mechanism to other reactions

   

• The reaction mechanisms which you have covered in this course are:
  • Free radical substitution
  • Electrophilic addition
  • Nucleophilic substitution
  • Elimination
  • Nucleophilic addition
  • Nucleophilic addition-elimination
  • Electrophilic substitution
  • Formation of amides

   

General Mechanisms

• The general mechanisms for each of these reactions are shown below
• Remember, these are just general mechanisms - for the exam you will have to draw them specific to the reaction in your exam question

Free radical substitution

Electrophilic addition

Nucleophilic substitution

Nucleophilic substitution with ammonia

Elimination
