MCQ
The strength of bonds formed by $2s-2s,2 p-2p$ and $2p -2s$ overlap has the  order
  • A
    $s-s > p-p > p-s$
  • B
    $s-s > p-s > p-p$
  • $p-p > p-s > s-s$
  • D
    $p-p > s- s > p-s$

Answer

Correct option: C.
$p-p > p-s > s-s$
c
When the orbit is same then the trend is like option B.

Maximum overlapping occurs in p coaxial overlapping then $\mathrm{p}-\mathrm{s}$ and then $\mathrm{s}$ -s.

When n increases the extent of overlapping decreases.

So, C is the correct answer.
