Question

reaction with bromine dissolved in ccl4 or bromine water is used as test for unsaturation alkemes and alkynes explaim with the help of suitable reaction​

Answer 1

Answer:

Bromine reacts, slowly, with C-H bonds via free-radical substitution. CCl4 solvent allows you to store bromine solutions long-term, because it cannot react with bromine.

Bromine reacts, slowly, with C-H bonds via free-radical substitution. CCl4 solvent allows you to store bromine solutions long-term, because it cannot react with bromine.Water is used in order to make bromohydrins, where you get Br and OH adding to the double bond. You can’t store bromine-water long-term because eventually the bromine will react with water to make hypobromic acid, HOBr, and HBr. This is analogous to what you get when you mix chlorine with water.

Answer 2

Answer:

Why is bromine used when dissolved in CCl4 or water in the reactions with alkenes?
