predict which compound would have the highest melting point and explain why.\na co - it is polar and has dipole - dipole forces.\nb co₂ - it has really strong dispersion forces.\nc sio₂ - it consists of a covalent network.\nd p₂o₅ - it has strong dipole - dipole forces.

predict which compound would have the highest melting point and explain why.\na co - it is polar and has dipole - dipole forces.\nb co₂ - it has really strong dispersion forces.\nc sio₂ - it consists of a covalent network.\nd p₂o₅ - it has strong dipole - dipole forces.

Answer

Brief Explanations:

Covalent network compounds have very high melting - points due to the strong covalent bonds throughout the entire network structure. CO has dipole - dipole forces which are relatively weaker than covalent network bonds. CO₂ has dispersion forces which are the weakest among the intermolecular forces for non - polar or slightly polar molecules. P₂O₅ has dipole - dipole forces but they are still weaker than the covalent bonds in a covalent network. SiO₂ is a covalent network compound.

Answer:

C. SiO₂ - It consists of a covalent network.
