Aldehydes Ketones and Carboxylic Acids Notes PDF – FAQs (Frequently Asked Questions)
1. How are Aldehydes Prepared?
Aldehydes can be prepared by any of the following reactions.
From the hydrogenation of acid chloride with palladium and barium sulphate as catalysts we prepare aldehydes.
Benzoyl chloride ⟶ benzaldehyde (catalyst – H2, Pd-BaSO4)
Nitriles reacting with stannous chloride in the presence of hydrochloric acid are reduced to imine, and its hydrolysis gives us aldehyde.
RCN + SnCl2 + HCl ⟶ RCH = NH ⟶ RCHO
Methylbenzene on reacting with chromyl chloride gives a chromium complex which on hydrolysis gives us the corresponding benzaldehyde.
Methyl benzene + CrO2Cl2 ⟶ Chromium complex ⟶ benzaldehyde
