Which of the following is an initiator molecule in the free radical polymerisation? Correct Answer Benzoyl peroxide

The whole process of free radical polymerisation starts off with a molecule called an initiator. This is a molecule like benzoyl peroxide. When they split, the pair of electrons in the bond which is broken will separate. This is unusual as electrons like to be in pairs whenever possible. When this split happens, we’re left with two fragments, called initiator fragments.
