Question

Alkyl halide is converted to alkane:

• A. Wurtz Reaction
• B. Birch reaction
• C. Sabatier-Senderens reaction
• D. Grignard reaction

Hint:

Wurtz Reaction = Alkyl halide + Na (dry ether) → Alkane. Useful for synthesizing symmetrical alkanes in organic chemistry.

Answer 1

The Correct Option is A

- The Wurtz reaction involves the coupling of two alkyl halides using sodium metal in dry ether, producing a higher alkane.
- General reaction: \[ 2R-X + 2Na \xrightarrow{\text{dry ether}} R-R + 2NaX \] where \( R \) is an alkyl group and \( X \) is a halide.
- It is mainly used for the synthesis of symmetric alkane from primary alkyl halides.
- The Birch reaction is a type of reduction reaction of aromatic rings using sodium and alcohol in liquid ammonia.
- The Sabatier-Senderens reaction is a hydrogenation of alkenes/alkynes using nickel catalysts.
- The Grignard reaction involves formation of C–C bonds using Grignard reagents, not direct conversion of alkyl halides to alkanes.
- Therefore, the correct reaction for converting alkyl halides to alkanes is the Wurtz Reaction.
