In Clemmensen reduction Zn-Hg/HCl and in in Wolf kishner reduction N2H4/KOH is used to generate
Correct answer: D. Nascent hydrogen
- A. Hydrogen peroxide
- B. Hydrogen molecules
- C. Oxygen
- D. Nascent hydrogen
Explanation
In Clemmenson reduction, Zn-Hg/HCl and in Wolf-Kishner reduction, N2H4/KOH generate nascent (active) hydrogen. In Clemmensen reduction, the generated nascent hydrogen is involved in the reduction of carbonyl groups, and in the Wolf-Kishner reduction, nascent hydrogen reduces carbonyl groups to hydrocarbons. The incorrect options focus on hydrogen peroxide, hydrogen molecules, and oxygen, which are not the products of these specific reductions.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
