A) O > S > Se >Te
B) S > O > Se > Te
C) S > Se > O > Te
D) O > S >Te > Se
Correct Answer: B
Solution :
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 the maximum tendency towards catenation.
