These two lessons are based on the aldehydes and ketones topic from the 2nd year of A Level specification.
The first lesson focuses first on a review of oxidation of alcohols from AS Level to form aldehydes and ketones. Naming practice and chemical tests are also included. The lesson then moves on the reduction of aldehydes and ketones to form alcohols. This includes the mechanism, equations and practice questions to consolidate.
The second lesson focuses on the conversion of aldehydes and ketones to hdroxynitriles. The mechanism is first considered in terms of how it can lead to a racemic mixture and why this has no effect on plane polarised light. There is practice naming hydroxynitriles as well as outlining the mechanism and identifying the products of reactions given the reactants.
There is also a homework task reviewing some mechanisms from AS Level.
Answers are given throughout.
