Question

Distinguish between homolysis bond fission and heterolysis bond fission

Answer 1

Homolysis or homolytic bond fission is a chemical bond dissociation of a molecule by a process where each of the fragments retains one of the originally bonded electrons whereas homolytic bond fission is that fission in which each atom in the bond has an electron which results in species called free radicals.

Answer 2

$\huge \underline \green{Answer:}$

✪ Bond fission: Bond fission is covalent bond breaking between symmetrical or unsymmetrical molecule.

Explanation:

✯There are two types of fission:

⭑Homolytic bond fission.

⭑Hetrolytic bond fission.

☆$\red{\text{</strong><strong>Homol</strong><strong>ytic</strong><strong> </strong><strong>bond</strong><strong> </strong><strong>fissio</strong><strong>n</strong><strong>:</strong><strong>}}$

⭒The symmetrical breaking of covalent bond between two atoms such a way that one electron of the shared paired forming free radical is called Homolytic bond fission.

⭒In this bond fission departing species are electrically neutral.

⭒They contain an unpaired electron hence they are para magnetic.

⭒The pre radicles are very reactive because they have incomplete octate.

⭒The bond fission take place at high temperature or in the presence of UV light or Hydrogen peroxide and in the non polar solvent or in gaseous state.

⭒Organic reaction obtained by Homolysis are called non polar reaction.

⭒The unsymmetrical breaking of covalent bond between two atom in a such a way that one of the departing atom retain the shared electron pair of the bond forming charged ions is called Hetrolytic bond fission.

⭒The fission takes place when two bonding atoms are deeper.

⭒The more electro negative atom retain electron pair and aquire negative charge and another atom gain positive charge.

⭒The fission takes place in polar solvent.

⭒Organic reaction processing by hetrolysis are called ionic or polar reaction.

⭒Hetrolytic fission does not takes place in gaseous state.
