B)compound A to be ionic and compound B to be covalent.
C)compound A to be covalent and compound B to be ionic.
D)both compounds to be ionic.

Question

Quizplus · Accepted Answer

Ionic compounds tend to have high melting points due to the strong electrostatic forces between the ions. Covalent compounds, on the other hand, have lower melting points because the forces between the molecules are weaker. Since compound A has a higher melting point than compound B, it is more likely to be ionic.
