Aldehydes & ketones can be converted to alkane. This reaction is called:
Correct answer: B. Wolff-Kishner reaction
- A. Ozonolysis
- B. Wolff-Kishner reaction
- C. Grignard reaction
- D. Friedel-Craft reaction
- E. None of these
Explanation
The Wolff-Kishner reaction is a chemical reaction used to reduce aldehydes or ketones to alkanes. This reaction involves the treatment of the carbonyl compound with hydrazine (NH₂NH₂) in the presence of a strong base (like potassium hydroxide, KOH) and heat. During the reaction, the carbonyl group (C=O) is converted into a methylene group (CH₂), effectively removing the oxygen atom. The reaction is performed under strongly basic conditions and is often used when acidic conditions are not suitable, unlike the Clemmensen reduction.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
