Which of the following is correct order of bond strength
I) 2S – 2S II) 2S – 2P III) 2P – 2P IV) 3S – 3S
I) 2S – 2S II) 2S – 2P III) 2P – 2P IV) 3S – 3S
View answer and explanation
Correct option: B
III > II > I > IV
Option B (III > II > I > IV) is correct because the strength of a sigma bond depends on the extent of overlapping, which is greater for 2p-2p than 2s-2p, 2s-2s, and 3s-3s.
