Question

In case of oxygen family (Group 16) :

• A. The tendency for catenation decreases markedly as we go down the group.
• B. Maximum coordination of oxygen is four due to lack of $d$-orbital but that of other elements is six due to presence of $d$-orbital.
• C. The tendency to form multiple bonds with $C,N$ and $O$ decreases as going down the group from $S$ to $Te$.
• D. All of the above are correct statements.

Answer 1

The correct option is D All of the above are correct statements.

In this group, oxygen and sulphur show catenation tendency. Catenation is maximum in sulphur upto 10 atoms.
Due to absence of d-orbitals, oxygen is unable to extend its valency and forms bond upto valency four.
Sulphur with higher valency.
