1.	5.PCls behaves as an ionic species in solid state. Why?ISECTION-B
Answer» In gaseous and molten state, it is a neutral molecule and its is PCl5 triagonal bipyramidal. This triagonal bipyramidal structure is present in non-polar solvents such as CS2and CCl4. However, In the solid state PCl5 exists as [PCl4]+and [PCl6]-, therefore, it is ionic in nature.
