according to Pauling, the electronegativity difference between two atoms A and B is directly proportional to?
Answers
Answer:
Bond energy
Pauling electronegativity:
EA-B = Bond enthalpy/Bond energy of A-B bond. All bond energies are in kJ / mol.
According to Pauling, the electronegativity difference between two atoms A and B is directly proportional to:
Explanation:
Electro-negativity
It is the force with which the electron attract its shared pair of electrons towards itself .
For example :
If bond is formed between homo-atomic molecules (having same type of atoms ), In them sharing of electrons occur the shared pair remain in the middle that is equal attraction by atoms towards shared pair.
• The hetro-atomic molecules (having different types of atoms in them) when sharing of electrons occur the shared pair do not lie in middle, it gets displaced towards more electronegative atom.
• So, it will acquire partial negative charge and other atom will acquire partial positive charge. Due to this the poles are developed and the bond formed is polar covalent bond.
It depends upon factors like :
The distance between charges : Electronegativity is inversely proportional to electronegativity .
The total charge : More is the charge , more is the electronegativity .
Size of an atom : It is inversely proportional to size of an atom .
