Question

What happen when ethyl bromide is treated with sodium metal in dry ether

Answer 1

Answer:

reaction of alkyl halide with sodium metal in the presence of dry weather results in formation of higher alkynes. when we treat ethyl Bromide made with sodium metal and ethyl alcohol in the presence of dry Ether it gives out butane and sodium chloride as a product.

Answer 2

Butane is formed when  ethyl bromide is treated with sodium metal in dry ether

When sodium metals are reacted with alkyl bromides in the presence of dry ether, alkanes are produced. This reaction is called Wurtz reaction.

Here, ethyl bromide () reacts with Na (in presence of dry ether).

Here 2 moles of the alkyl bromides are used and from the 2 moles, the Br⁻ ions eliminate and interact with 2 moles of Na⁺ to form 2 moles of NaBr.

The remaing 2 C₂H₅⁺ attach with themselves to form butane, C₄H₁₀.

The reaction is as follows:

2 C₂H₅Br  + 2 Na → C₄H₁₀ + 2 NaBr
