Question

Which of the following represents s - s, s - p and p - p overlap?

• A.
• B.
• C.
• D.

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A
B
C
D

A covalent bond is formed when two atoms approches each other closely and the overlaping of valence orbitals take place. These overlaping of orbitals are of fallowing types:

s-s overlap $\to$ Overlap of two half filled s-orbitals along the inter-nuclear axis.

s-p overlap $\to$ Overlap between half-filled p-orbitals of one atom and half-filled s-orbitals of another atom.

p-p overlap $\to$ Overlap between half-filled p-orbitals of the two approaching atoms.
