Question

By heating phenyl bromide with methyiodide with sodium dry ether we get a) Benzene b) Toluene c) xylene d) Benzaldehyde.
​

Answer 1

Explanation:

Butane is formed.

This is an example of Wurtz Reaction. Here 2 moles of alkyl halide react with sodium in presence of Dry Ether to produce an alkane giving off the respective sodium halide as by product.

C2H5Br + Na + Na + BrC2H5 → C4H10 + 2 NaBr

(THE PURPOSE OF WRITING THE REACTION IN THIS WAY IS TO ONLY EXPLAIN YOU HOW THE PRODUCTS ARE FORMED.)

*NOTE - There's another reaction called Frankland Reaction which works on the same principle as in this reaction. (Only Zn is used in place of Na.)

Thank you! :)
