The table below shows the normal boiling points of benzene and benzene derivatives.

(a) How many of these compounds exhibit dispersion interactions?

Hey everyone, we're asked given the following car box silic acid derivatives, which statement is true. Now let's go ahead and look at our statements for a. We have all of the compounds have hydrogen bonding. Now this statement is going to be false and the reason why is because our castle chlorides and our acid anhydride are unable to hydrogen bond. So that eliminates a. Next looking at B. We have all of the compounds do not have London dispersion forces. This statement is going to be false as well because all of these compounds do have London dispersion forces present. Next looking at sea, we have all of the compounds have ion dipole forces. This statement is also going to be incorrect and the reason why is because not all of the molecules exhibit ion dipole forces. Now, if one of these were to become an ion and interact favorably with a polar molecule or a functional group, then we would have that ion dipole force present. And lastly we have all of the compounds do not have similar attractive forces. And this statement is going to be our answer because as we discussed, each of them have different attractive forces. Now, I hope that made sense. And let us know if you have any questions
