Substitution reactions Replacement of a molecule or set/group of the substrate by any another type of atom or group is termed as substitution reactions. Examples :
seawater contains 0.75g of Fe+3 per kilogram of water. What is the concentration of Fe_3 in ppm?
Delocalisation of electrons in conjugated system is called resonance. For example there is delocalisation of electrons in benzene ,hence we write kekule structure for benzen.
