Addition polymerization: It involves following three mechanisms:
1. Free radical polymerization
2. Ionic polymerization mechanism
3. Coordination polymerization mechanism
Free-radical polymerization: It involves following steps:
Initial step
1. Production of free radicals by the decomposition of compounds called initiators
R-R = 2R
Initiator free radicals
The decomposition of the initiator is splitting into two identical fragments called homiletic decomposition, where each fragment carrier's one unpaired electron with it called free radical.
Chain propagation step: The free radical (R) produced in the chain initiation step adds to an alkenes to form a new free radical, which then reacts with additional monomers in a chain reaction:
R + H2C = RCH2CH2
RCH2CH2 +CH2 = RCH2CH2 :CH2
factors that effect the solubility of a solute The solubility of a solute is effected by three factors like 1) Nature of solute 2) Nature of solvent 3) Temperature Nature

A 100 gal tank contains 10 lb of water. The tank is filled by two inlet streams, one of pure water and one of pure ethanol. The flow rate of both streams is 10 gal/min. Calculate t
(i) Illutrate integrated rate law and derive it for first order reaction. (ii) Why coal does not burn by itself in air but once initiated by flame, it continues to burn?
fiehes test means result if positive result always color change if negative color change or not
In polar covalent molecule, one atom gets positive charge and the other one takes negative charge as known as dipole.
Ionic bonds are usually formed by combination of elements with: (1) High ionisation potential and low electron affinity (2) Low ionisation potential and high electron affini
