FREE RADICAL SUB

Question 1

Homolytic fission (needs uv light to break the bond)

Answer 1

When the covalent bond breaks, and one
electron goes to each of the atoms in the bond. Now each atom has an unpaired of electrons

Question 2

Free Radicals

Answer 2

An atom or atoms with an unpaired electron

Question 3

Initiation phase

Answer 3

initiates by the breaking of the bonds by
homolytic fission to make two free radicals. (UV LIGHT)

Question 4

Propagation
(goes like a Chain)

Answer 4

There are two phases here

Free radical generated in the initiation step reacts with a molecule to form a new radical and a new molecule, thereby sustaining the chain reaction.This process continues as the newly formed radical reacts with another molecule, leading to the propagation of the radical chain.

Question 5

Termination

Answer 5

it terminates when any two radicals combine
forming a new molecule.
