Question

Give a brief account of the halides of group 16 elements.

Answer 1

1. Group 16 elements include oxygen (O), sulphur (S), selenium (Se), and tellurium (Te), which form various halides.
2. These halides include fluorides, chlorides, bromides, and iodides with different compositions.
3. Oxygen forms compounds like oxygen difluoride (OF₂) and halogen oxides (Cl₂O, Br₂O, I₂O₅).
4. Sulphur forms halides such as SF₂, SF₄, SF₆; SCl₂, SCl₄; SBr₂; and S₂I₂.
5. Selenium forms SeF₄, SeF₆; SeCl₂, SeCl₄; and SeBr₂, SeBr₄ halides.
6. Tellurium forms TeF₄, TeF₆; TeCl₂, TeCl₄; and TeBr₂ halides.
7. These halides exhibit various oxidation states and structural features depending on the element and halogen.
8. Fluorides tend to be more stable and covalent compared to other halides.
9. The halides have important applications in industry and chemistry due to their varied reactivity and properties.
