Question
Oxygen molecule is formed by
A.
one axial $$s{\text{ - }}s$$ overlap and one $$p{\text{ - }}p$$ axial overlap
B.
two $$p{\text{ - }}p$$ axial overlaps
C.
two $$p{\text{ - }}p$$ sidewise overlaps
D.
one $$p{\text{ - }}p$$ axial and one $$p{\text{ - }}p$$ sidewise overlap
Answer :
one $$p{\text{ - }}p$$ axial and one $$p{\text{ - }}p$$ sidewise overlap
Solution :
$$\sigma $$ bond of $$O = O$$ is formed by axial overlapping of $$p{\text{ - }}p$$ orbital while $$\pi $$ bond is formed by sidewise overlapping of $$p - p$$ orbital.
