Question

please help with this question for the circled substances:) TIA

PART B-MELTING POINTS OF SOME ORGANIC SUBSTANCES 7. Cirele the pair of substances of which you measured the melting point range 2-naphthol (A) and naphthalene (B) benzophenone (W) and benzil (B Complete the following table: [6 marka) Hint Molecules containing only Cand H can be assumed to be non polar. Present in в Present in Stronger in which subatance? Why? Intermolecular Force A (yes or no) (yes or no) London Dispersion Dipole-Dipole Hydrogen Bonding Which of the two substances that you measured has the higher melting point? Why? (3 marks To answer this question, you must summarine all of the information in the table above. Consider all of the intermoleeular forces that are present, and also not present, in each substance. Then compare their relative strengths in both substances. Finally, assess both substances as to the total strength of their intermolecular forces. Please use the chemical's real names when answering, not A and B)

Benzil has higher melting point 94.8 degree compared to benzophenone has melting point 48.5 degree. it means that it takes less intermolecular forces to break the bonds of benzophenone. The bonds holding in benzophenone is weaker than in benzil.
