Question

8. Indicate whether the following reaction is an oxidation or reduction or neither. (4) CH3 OCH3 SH Y-Y mi-in ~ -Y TT OH

Answer 1

First reaction: Oxidation

Second reaction: Reduction

Third reaction: Reduction

Fourth reaction: Oxidation

OMe Oxidation; Oxygen count increased in the product. 2SH Reduction, dithiane was reduced to thiol. Ratio of hydrogens in product is more than reactant Reduction Number of hydrogens in product is more than reactant. Unsaturation was reduced to saturation. Oxidation; Oxygen count increased in the product and Electron density at carbon reduced in the product than reactant
