This webinar will provide your students with the opportunity to revisit challenging topics in organic chemistry. Following a brief consideration of condensation polymers, we look at amino acids and chirality. Evidence for the structure and bonding of benzene is next and then we move to NMR analysis and tackle a ‘levels of response’ question involving data from NMR and mass spectrometry to solve a crime scene mystery.

The session will give students the opportunity to receive guidance from experts with A Level Chemistry examining experience. The webinar will also equip students with what they need for the exam and to be well prepared and knowing on how to access those high grades.


  • Develop understanding of the challenging topics in organic chemistry
  • Gain insights into what an examiner is looking for when answering a question about the chirality of amino acids
  • Consider evidence for the structure and bonding in benzene and use this to understand why it reacts with an electrophilic substitution mechanism
  • Understand NMR spectra and combine this with mass spectrometry data to suggest the structure of a compound in a ‘levels of response’ question


  • All students of A level Chemistry


4.00pm – Introduction, welcome and sound check

4.05pm – Polymers, polyamides and amino acids

  • Activities to revise organic structures, terminology and reactions
  • Review exemplar questions and answers finding out how to improve marks
  • Students mark three candidate answers based on the optical isomerism of amino acids

4.30pm – The structure and bonding in benzene

  • Students use data to evidence the structure of benzene and how it reacts with electrophiles
  • Provide practical advice on how students can improve data analysis
  • Exam technique, exam tactics for these questions

4.45pm – Understanding NMR spectra

  • Activities to consolidate understanding  of NMR spectra and combine this with mass spectrometry data
  • How to answer a ‘levels of response’ question for top marks
  • Analysing sample responses to NMR spectra questions

5.00pm – Finish
