Alcohols (Edexcel)

4 well structured chemistry lessons covering topics on Alcohols (Year 12) suitable for the Edexcel specification.

Lesson 1: Properties of Alcohols

1. To identify and explain the intermolecular forces that are present in alcohol molecules
2. To explain the water solubility of alcohols, their low volatility and their trend in boiling points
   3.To classify alcohols as primary, secondary or tertiary alcohols

Lesson 2: Oxidation of Alcohols

1. To know that alcohols can undergo combustion reactions in the presence of oxygen
2. To know alcohols can be oxidised by an oxidising agent called acidified potassium dichromate
3. To know the products and reaction conditions for the oxidation of primary alcohols to aldehydes and carboxylic acids
4. To know the products and reaction conditions for the oxidation of secondary alcohols to ketones

Lesson 3: Dehydration and Halogenation of Alcohols

1. To know that alkenes can be formed from alcohols by acid-catalysed elimination reactions
2. To draw the structure of alkenes formed from alcohols by acid-catalysed elimination reactions
3. To understand the reactions of alcohols with halogenating agents: PCl5, KBr & H2SO4 and PI3

Lesson 4: Industrial Production of Ethanol and Biofuels

1. To describe the industrial synthesis of ethanol using mechanisms and equations (where applicable) by:

i) The hydration of ethene
ii) The fermentation of glucose

1. To construct equations to support the statement that ethanol produced by fermentation is a carbon neutral fuel and give reasons why this statement is not valid

2. To discuss the environmental (including ethical) issues linked to decision making about biofuel use.

This is because planning your own lessons including using your own lesson PowerPoints is a fundamental skill of a qualified/unqualified teacher that will be reviewed during these scenarios outlined above
