Question

Which one of the following statements is not true in respect of propeties of interhalogen compounds?

• A. They are all covalent compounds
• B. They are volatile solids or liquids except $ClF$
• C. $I{F}_5$ has square pyramidal structure
• D. They are all paramagnetic in nature
• E. $Br{F}_3$ is used in the preparation of $U{F}_6$ in the enrichment of ${}^{235}U$

Answer 1

The correct option is D They are all paramagnetic in nature

Interhalogen compounds are covalent molecules.

With the exception of $ClF$ (which is a gas at $298K$), all are volatile solids or liquids.

They are diamagnetic in nature.

The shape of $I{F}_5$ is square pyramidal.

These compounds are very useful fluorinating agents. e.g., $Br{F}_3$ in the enrichment of ${}^{235}U$.
