Edexcel IAL Chemistry A2 20.2 Grignard reagents and chain extension
Choose the organomagnesium halide from the product: Grignard reagents act as nucleophiles, then hydrolysis gives alcohols or carboxylic acids.
How this is tested
- Select magnesium and dry ether to form a Grignard reagent from a halogenoalkane.
- Predict alcohol or carboxylic acid products after reaction with carbonyl compounds or CO2.
- Choose the Grignard reagent and carbonyl partner needed for a target alcohol.
