Problem
Three hypothetical substances have the following properties:
• Substance X: molar mass 58 g mol−1, dipole moment 1.5 D
• Substance Y: molar mass 60 g mol−1, dipole moment 0.0 D
• Substance Z: molar mass 44 g mol−1, dipole moment 2.8 D
Based on these data, which ranking from weakest to strongest overall intermolecular attractions is most reasonable?
(a) Z < X < Y
(b) X < Y < Z
(c) Y < X < Z
(d) Y < Z < X
