Subjective Type

Account for the following: Sulphur exhibits greater tendency for catenation than selenium.

Solution

As we move from $$S$$ to $$Se$$, the atomic size increases and hence the strength of $$E-E$$ bond decreases. Thus, $$S-S$$ bond is much stronger than $$Se-Se$$ bond.
Consequently, $$S$$ shows greater tendency for catenation than selenium.
