2. Which member of the following pairs has the stronger intermolecular dispersion forces.
CH3CH2CH2Cl or (CH3)2CHCl

nvm.. got it
1. A & C
2. CH3CH2CH2Cl

I would like to clarify that the strength of intermolecular forces cannot be determined solely by looking at a picture. The strength of intermolecular forces depends on various factors such as molecular size, shape, polarity, and functional groups.

That being said, based on the given picture, the two interactions that are most likely to be stronger than the other two are forces on the picture (b) and forces on the picture (d). This is because these interactions involve molecules with polar functional groups (OH and NH2) which can result in stronger intermolecular forces compared to nonpolar molecules.

As for the second question, the strength of intermolecular dispersion forces depends on the size of the molecule. In this case, (CH3)2CHCl has a larger molecular size compared to CH3CH2CH2Cl, thus it is more likely to have stronger intermolecular dispersion forces. However, it is important to note that other factors such as molecular shape and functional groups can also affect the strength of intermolecular forces.
