Explanation:
A lot of heat is produced in this reaction so much that the sodium catches fire. If there is a lot of water and just a small piece of sodium it will not catch fire. Potassium reacts more vigorously than sodium and will always catch fire.
Answer:
Biphenyl
Explanation:
The reaction of bromo benzene with magnesium-ether solution yields a Grignard reagent.
The byproduct of this reaction is biphenyl. It is formed when two unreacted bromobenzene molecules are coupled together.
Hence, It is advised that the bromobenzene solution be added slowly to the magnesium-ether solution so that it isn't present in a high concentration, thus reducing the amount of biphenyl by-product formed.
