WebIn the polymerization of ethene to polythene by heating or exposing to light by using a small amount of benzoyl peroxide initiator. The phenyl free radical formed by peroxide is added to the ethene double bond and hence formed a new larger free radical. Also Read: Chemical Bonding. It is called a chain initiation step. WebEthene polythene. 3. At constant temperature and pressure, the volumeof a gas is directly proportional to the number of molecules. This relationship between volume and number of molecules of a gas at constant temperature and pressure is known as Avagadro’s law. 4. When molten sodium chloride ( 𝑎𝐶𝑙)is electrolysed,the gas liberated at ...
