Why does the pi bond or which involves overlap of p orbital only? why is the sigma bond of p-p orbital much stronger than P-S orbital which is much stronger than S-S orbital?

Q. Explain why a Sigma $\left(\sigma \right)$- bond is stronger than a Pi$\left(\pi \right)$- bond?

Q. A $\sigma$ bond may be formed by the overlap of 2 atomic orbitals of atoms A and B. If the bond is formed along the x-axis, which of the following overlaps is acceptable?

Q. Select the correct statement(s) out of the following:
i) A sigma (s) bond is formed when two s-orbitals overlap.
ii) A pi (p) bond is formed when two p-orbitals overlap sideways.
iii) An sigma bond is weaker than pi bond.

Q. The type of delocalization involving sigma bond orbitals with $\pi$ bond or vacant orbital is called:

Q. A sigma $\left(\sigma \right)$ bond is stronger than a pi $\left(\pi \right)$ bond.
