Question

pls explain these concepts in simple and understandable manner with examples....
valence bond theory and molecular orbital theory...​

Answer 1

Answer:

Valence bond (VB) theory assumes that all bonds are localised bonds formed between two atoms by the donation of an electron from each atom. This is actually an invalid assumption because many atoms bond using delocalised electrons. In molecular oxygen VB theory predict that there are no unpaired electrons.

Kinetic Molecular Theory states that gas particles are in constant motion and exhibit perfectly elastic collisions. Kinetic Molecular Theory can be used to explain both Charles' and Boyle's Laws. The average kinetic energy of a collection of gas particles is directly proportional to absolute temperature only.
