Question

Why chlorination is faster than bromination?

Answer 1

Chlorination and bromination:

1. Bromination is a chemical process in which a compound reacts with bromine, resulting in the addition of bromine to the component.
2. The technique of adding chlorine to drinking water to kill parasites, germs, and viruses is known as chlorination.
3. To achieve safe chlorine levels in drinking water, a variety of techniques can be used.

The reason for chlorination is faster than bromination are:

1. The intensity of the attraction is also affected by the number of full electron shells between the nucleus and the electron - this is known as shielding.
2. Because a bromine atom has one more complete shell than a chlorine atom, it has more shielding, therefore the nucleus-electron attraction is weaker.
3. Although the bromine nucleus is more positively charged than the chlorine nucleus, the increased radius and additional shielding in the bromine atom outweigh this factor, resulting in an electron being more easily attracted into the outer shell of a chlorine atom than the outer shell of a bromine atom, making chlorine more reactive.
