The strength of bonds by overlapping of atomic orbitals is in order

Options

A. `2s-2s gt 2s-2p gt 2p-2p`
B. `2s-2p lt 2s-2s lt 2p-2p`
C. `2s-2s lt 2s-2p lt 2p-2p`
D. `2p-2p lt 2s-2s lt 2s-2p`

Answer

C

Explanation

Bond strength depends on extent of overlapping.
Overlapping directional character `prop (1)/("size")`. Directional character of p orbital is more than that of s-orbital
