ELI5: Why is bleach so toxic to all living things?
gpt
Because it has reactive chlorine in it.

Chlorine tends to form strong chemical bonds with organic molecules.These bonds change how the rest of the molecule reacts and can displace certain groups of elements from the molecule, or even trigger a chain of reactions that result in a drastically different molecule.

Living organisms depend on consistant reactions in order to function, so the disruption of the chlorine screws up their patern, thus preventing them from continuing life-functions.
