Here's the step-by-step process: 1. **Oxidation of Ethanol to Acetaldehyde**: Ethanol is first oxidized to acetaldehyde (CH₃CHO) using an oxidizing agent like potassium dichromate (K₂Cr₂O₇) under acidic conditions: C2H5OH---- K2Cr2{O}7/H^+ ---------CH3CHO + H2O 2. then we follow same method **Formation of Acetaldehyde reacts with hydrogen cyanide (HCN) This method involves toxic reagents like HCN and is primarily of academic interest. Industrially, lactic acid is typically produced via *fermentation of sugars* (e.g., glucose) by lactic acid bacteria (e.g., *Lactobacillus*). Ethanol is not a common direct precursor in large-scale production.
