Question

explain the formation of oxygen molecule on the basis of valency bond theory​

Answer 1

Answer:

Formation of O _{ 2 } molecule by valence bond theory : ... Oxygen atom has six electrons in its valence shell. It requires two more electrons to get Octet in its valence shell. Therefore oxygen atoms come close and each oxygen atom contributes two electrons for bonding

Answer 2

Answer:

Formation of o_O

according to vespert theory

(1) Electronic configuration of 'O' is 1s2 2s2 2px2 spy1 spz1.

(2) If the py orbital of one 'O' atom overlaps the py orbital of other 'O' atom along internuclear axis, a σ py – py bond is formed.

(3) pz orbital of oxygen atom overlap laterally, perpendicular to inter nuclear axis giving a π pz – pz bond.

(4) So O2 molecule has a double bond between the two oxygen atoms.
