Question

Choose the answer which presents the chemical formulas for two substances in order of decreasing melting point (highest melting point first) and gives a valid reason for this order.

a) CO > C(diamond) because CO has a triple bond and stronger dispersion forces.

b) C₆Cl₆ > C₆H₆ due to ionic bonding in C₆Cl₆ not present in C₆H₆.

c) CaO > ScN due to ionic forces in CaO not present in ScN.

d) Al > H₂O due to strong metallic bonding in Al, versus weaker hydrogen bonding in H₂O.

e) CF₄ > XeF₄ due to ionic bonding in CF₄ not present in XeF₄.
