Homework Answers
Water - polar
Hexane - nonpolar
Methanol - polar
1-octanol - polar
Acetone - polar
3-pentanone - polar
2-pentanol - polar
Ethylene glycol - polar
(Ethylene glycol may seem to be nonpolar as it has two terminal hydroxyl group seems canceling out each others dipole moment. But if you draw newman projection of ethylene glycol, the gauche confirmation is most stable which contributes most and hence making it polar.)
(Normal hydrocarbon chains are generally nonpolar.)
Hydrocarbon chains having hydroxyl group is polar.
Ketonic group is always polar.

PART IV. MISCIBILITY OF TWO LIQUIDS
1. For the first two liquids in Table IV-B (the solvents in the
miscibility tests), use the molecular structures provided in the
Introduction to identify each liquid as polar or nonpolar. Put an X
in the appropriate column.
2. For the remaining liquids in Table IV-B, determine if they
are primarily polar, primarily nonpolar, or both polar and polar
based on your observations in Table III-A and based on the polarity
of the solvent....

1st attempt M See Periodic Table Two liquids - one polar, one nonpolar - have the same molar mass. Which one has the higher boiling point? Choose one: A. The polar liquid will have the higher boiling point, since its molecules have dipole-dipole interactions. B. They will have similar boiling points, since the dispersion forces depend upon molar mass. C. The nonpolar liquid will have the higher boiling point, since its molecules are more loosely held together. D. The nonpolar...

2. Identify the strongest type of intermolecular forces in acetone, ethanol, water and hexane. (Structures listed on page 15.) Experiment 2 Intermolecular Forces There are three general types of intermolecular forces. All substances exhibit London Dispersion Forces (LDF), and they are generally the weakest of the three types. These London forces are due to the attractions between small, temporary dipoles that arise from the constant, random movement of the electrons in a substance. As molar mass increases, the size of...
