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

Options

A. a) They are all covalent compounds
B. b) They are volatile solids or liquids except CIF
C. c) `IF_(5)` has square pyramidal structure
D. d) They are all paramagnetic in nature

Answer

D

Explanation

Interhalogen compounds are covalent molecules. With the exception of CIF (which is a gas at 298 K), all are volatile solids or liquids. They are diamagnetic in nature. The shape of `IF_(5)` is square pyramidal. These compounds are very useful flourinating agents. e.g., `CIF_(3) and BrF_(3)` are used for production of `UF_(6)` in the enrichment of `""^(235) U.`
