What is the most significant intermolecular force acting between molecules of CH3Cl? Explain your answer.
Answers
Answer:
Dipole-dipole interactions occur between polar molecules.
An example of a polar molecule would be CH3Cl, or chloromethane. Chloromethane is a carbon with three hydrogens and a chlorine attached to it.
The carbon-hydrogen bonds are essentially non-polar, but the carbon-chlorine bond is polar. This results in a slightly positive charge on the carbon and a slightly negative charge on the chlorine, because it is more electronegative and will suck up those electrons to hold on to it.
This results in a much stronger attraction between the molecules in their solid and the liquid forms than in their vapor form. In the vapor, there is still this attraction if they come close to each other, but since vapor molecules tend to be so far apart, this force isn’t as strong. The result of this dipole-dipole interaction though, is that molecules want stay as the liquid for as long as possible, because there are intermolecular forces holding them together.
