(1) Molecules are made of bonded atoms and the atoms contains electron, proton and neutron. An organic reaction mechanism is a complete, step-by-step account of how a reaction of organic compounds takes place.
Define in details for electron energy. (8 points)
(2) A radical substitution reaction is a reaction which occurs by a free radical mechanism and results in the substitution of one or more atoms or groups present in the substrate by different atoms or groups. A radical contains an atom that does not have an octet of electrons and halfheaded arrows are used to show the movement of electrons in radical processes.
Illustrates the radical chain reaction process under the heat. (4 points)
