The highest catenation ability is shown by
- AOxygen
- ✓Sulphur
- CSelenium
- DTellurium
✓
Answer
Correct option: B.
Sulphur
b
The greater the element-element bond strength, the higher is the tendency towards catenation.
The greater the element-element bond strength, the higher is the tendency towards catenation.
As the size increases from $S$ to $Te$, the bond dissociation energy decreases. $O -O$ bond energy is, however, smaller than that of $S-S$ because of inter electronic repulsions within the smaller size of oxygen atoms.
Thus, sulphur has a maximum tendency towards catenation.
