ABOUT THIS WEBINAR

This webinar will concentrate on some of the more unusual questions associated with Group 7 chemistry.  Students often do well with recalling knowledge from this topic (such as the observations with silver nitrate) but struggle to apply this knowledge.  The session will focus on questions about mixtures of halides, using the observations to plan a separation and testing of haloalkanes. It will also help students with techniques and tips to help students to structure their answers in an exam.

BENEFITS OF THIS WEBINAR

  • Consolidate and improve knowledge of Group 7 Chemistry
  • Promote understanding of Group 7 Chemistry to allow application to unfamiliar situations
  • Review exemplar questions and answers, finding out how to improve exam skills
  • Work through tips and examples for approaches to organic chemistry questions
  • Set a grounding for similar questions found in Year 13 study (i.e transition metals, acyl chlorides, etc)

WHO SHOULD ATTEND

  • All students of A level Chemistry

PROGRAMME

4.00pm – Introduction, welcome and sound check

4.05 pm:  Mixtures of halides

  • Revision of the basic tests for halides – including why we use acid, which acid and why ammonia is used
  • A look at the expected observations with the silver nitrate test and halide mixtures
  • How to structure an answer to explain the observations with a mixture

4.20pm: Using observations to plan a separation

  • Tips to help with what a question is asking using halide separation as an example
  • What is the process – how can separation be achieved
  • Structuring the answer – how to explain the method for maximum marks
  • Pitfalls – Where do students lose marks in an exam

4.40pm: Haloalkane testing

  • A look at the chemistry – why is this situation different
  • Steps in the method – What is each stage about and how can you explain this?
  • Other situations when we can/cannot use just silver nitrate

4.55pm: Final tips
