Question

The strength of sigma bonds formed by axial overlap of s- orp-orbitals of 2nd shell of participating atoms decreases as:

Answer 1

Solution:-

$p$-orbitals afford maximum axial overlap and $s$-orbitals have minimum.

Thus the decreasing order of extent of overlap among $2s$ and $2p$ orbitals is-

$p-p>p-s>ss$.
