Aromaticity - Aromatic compounds - Huckel's Rule - Crack Chemistry

The compound which behave like benzene are called Aromatic compound. An aromatic compound must satisfy the following conditions :-

• Cyclic and planer structure• Equal bond length• Chemical stability• Ability to undergo substitution reactions• Ability to sustain on induced diamagnetic ring current diatrophic• Conjugated system of π-electrons with effective Delocalisation• All carbon present in the ring must be sp² - Hybridsed

Electron Affinity - Electron Gain Enthalpy - CrackChemistry :

As you know, Electron Gain Enthalpy (Electron Affinity ) is direct opposite to the Ionisation Energy Ionisation Energy is the energy required to remove an electron from neutral atom.On contrast,Electron gain enthalpy is the energy required or released whenever the electron is added to neutral atom. Whenever the electron added to an neutral atom,it gets support from nucleus as in the form of Nuclear Charge (attraction force) But it also get repulsion from another electrons that present in the atom.This is why electron gain enthalpy is depend upon the nature of atom as well as its requirements.
