(d) butane

hope it helps you

Answer 2

Butane is formed by the action of sodium on iodo ethane

Option (d) is the correct answer

Explanation:

• This reaction is the Wurtz reaction where Butane is formed by the action of sodium on iodo ethane or alkyl halide.
• Wurtz reaction$C2H5I +2Na +C2H5I -------- C2H5-C2H5 +2NaI$
• When sodium reacts with ethyl iodide, in the presence of dry ether it forms hydrocarbon Butane
• This reaction is a coupling reaction. which was named after Adolph Wurtz.
• It is an important reaction in organometallic chemistry where two alkyl halide reacts to form a higher alkane.
