Answer

Brief Explanations:

Ionic compounds are typically brittle solids with high melting - points. Compound Z is a brittle solid and has a high melting point of 801°C, which are characteristic properties of ionic compounds. Compounds W and Y with molecular structures are less likely to be ionic as ionic compounds have a lattice structure. Compound X not conducting electricity in water is also not typical of ionic compounds which usually dissociate in water to conduct electricity.

Answer:

Z
