Explain why nonpolar molecules usually have much lower surface tension than polar ones.
Which of the following molecules is polar (please explain WHY) --- SF2. --- Br2. --- CCl4. --- BCl3. --- SO3.
Arrange the following molecules from least polar to most polar, explain your reasoning (6 points) 2. a. CH, b. CF.CI, c. CF.H, e. CCl,H
Because water molecules can form a variety of hydrogen bonds with each other, water molecules tend to have more configurations when they are by themselves than when they are mixed with other molecules that cannot form hydrogen bonds. Imagine that the interactions between water molecules and the molecules of a non polar substance A (W-A interactions) are stronger than the W-W and A-A interactions. In this case one can predict that: Water Properties Homework. Unanswered Because water molecules can form...

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...
7. Diethyl ether and 1-butanol are isomers their boiling points are very different. Explain why these two compounds have dramatically different boiling points. (2 pt.) CH3CH2OCH CH3 CH3CH2CH2CH OH Diethyl ether butanol
The first law involves the change in internal energy. Explain why the change in internal energy does not include the change in gravitational potential energy of the gaseous molecules.
Why does benzene have a much higher boiling point (80。c) than hexane (69。c), even though they have the same number of carbons? A) Benzene is much more polar than hexane which enhances the attractive forces between molecules and raises the boiling point. B) Benzene has fewer hydrogens than hexane. C) Benzene is planar and has delocalized electron density which increases the attractive forces between molecules and raises the boiling point. D) Benzene can covalently bond to another benzene molecule which...
