Question

True or False: Ionic compounds usually have higher melting points than covalent compounds

Answer 1

Ionic compounds usually have higher melting points than covalent compounds.

Step-by-step explanation:

Ionic compounds usually have higher melting points than covalent compounds. Ionic compounds are hard solids with high melting points because they are held together by strong ionic bonds in a 3D array of crystal lattices.

Covalent compounds that exist as giant molecules have higher melting points than ionic compounds.

For example, SiO₂ present in sand and quartz is a hard solid that melts at 1,710 °C.
