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.
Describe why shielding is more effective by electrons in a shell of lower principle quantum number than by electrons having the similar principle quantum number.
The equilibrium cell potential of the galvanic cell Pt | H 2 (g, f =1 bar) HCl (aq, 0.500mol kg -1 ) | Cl 2 (g, f =1 bar) | Pt is found to be E cell, eq = 1.410V at 298.15
