Study Notes
- The process involves the conversion of primary alcohols to primary alkyl halides using HBr and H2SO4.
- Propene is then reacted with ethyl magnesium chloride to produce a primary alcohol called propan-1-ol.
- Propan-1-ol is treated with a Grignard reagent to form a secondary alcohol.
- If one wants to convert an alcohol into an aldehyde, it can be done by reacting it with copper at 573 Kelvin to form an aldehyde like CH3CHO.
- The aldehyde can then be treated with a Grignard reagent to introduce a new carbon chain.
- The Grignard reagent is important as it can help in increasing the carbon chain length.
- By reacting benzal chloride with water, benzaldehyde can be produced.
- Benzaldehyde can be further converted to benzoic acid by reacting it with KMnO4.
- Acetophenone can be converted to benzoic acid by reacting it with I2 in the presence of KOH.
- The text also discusses the conversion of ethanoic acid to acetic anhydride by reacting it with SOCl2.
- The process of converting benzoyl chloride to benzaldehyde involves a Clemmensen reduction reaction.
- The text emphasizes different reactions and conversions involving various chemical compounds and reagents.
