Question
Compared to other group 16 elements, the anomalous behavior of Oxygen is due to:
Answer: Option C
:
C
Among the Chalcogens, Oxygen shows considerable anomalies. For instance, Oxygen exists as a diatomic gas while the other chalcogens are all solids at room temperature and 1atm pressure. Further, oxygen forms strong and stablepπ−pπdouble bonds (as in the case of O2 molecule) whereas the other elements tend not to. Also, the Oxygen - Oxygen single bond is weaker compared to the Element - Element single bonds of other chalcogens.
All this can be attributedto the small atomic size and high electro negativity of Oxygen.
