Answer to Problem 90A

Basic difference between sulfur hexafluoride and disulfur tetrafluoride is structure and molecular formula.

Explanation of Solution

Sulfur hexafluoride $\left({\text{SF}}_{\text{6}}\right)$ contains one sulfur atom and six fluorine atom. In this compound, six fluorine atoms are attached to one sulfur atom. Structure of Sulfur hexafluoride $\left({\text{SF}}_{\text{6}}\right)$ is as follows:

Molecular formula of disulfur tetrafluoride is ${\text{S}}_{\text{2}}{\text{F}}_{\text{4}}$. It contains four fluorine atoms that are attached to two sulfur atoms. Structure of ${\text{S}}_{\text{2}}{\text{F}}_{\text{4}}$ is as follows:

Conclusion

Covalent bonds are chemical bond where two or more atoms share one or more electron pairs. Covalent bonds are formed between sulfur and fluorine.
