What is the differnce between electrin gain entalpy and electronegativity |
| Answer» Both electron gain enthalpy and electronegativity referred to tendency to attract electron but electron gain enthalpy refers to the introduction of electron to the outer most shell of an isolated gaseous atom where as electronegativity refers to the tendency of an atom of an element to attract tha shared pair of eletron towards itself in a covolent bond<br>Electron gain enthalpy means that the energy released when an electron is added in a gaseous isolated atom or ion.Electronegativity means the ability of an atom in a chemical compound to attract shared electrons towards itself is called electro negativity. | |

Plz explain me the term hybridization |
| Answer» Concept of mixing two atomic orbitals with the same energy levels to give a degenerated new type of orbitals<br>Atoms rearrange their atomic orbitals when bonding to produce orbitals with shapes more suitable for the bonding process. This is called hybridisation. It is performed by almost all atoms when bonding although carbon provided the easiest examples to show. It is easy to recognise the hybridisation used by simply observing the double or triple bonds.Only single bond = sp3 hybridisation1 double bond = sp2 hybridisation1 triple bond = sp hybridisation | |
