Chemistry - Complete P-block Question with Solution | TestHub

Concept: $\mathrm{p}\pi -\mathrm{p}\pi$ bonding vs $3\mathrm{p}-3\mathrm{p}$ overlap, Steric constraints.

Solution:

(A) and (B) are direct results.

(C) is due to both size and lack of d-orbitals.

is due to the efficiency of $2p\pi -2p\pi$ bonding allowing for a stable diatomic molecule, which Sulfur cannot do effectively.
