Do you know why the answer is pdpd? I thought it was Hydrogen bonding :/

So the answer is pdpd as there is a permanent dipole in both molecules
Hope that helps

it cant be hydrogen bonding because the hydrogen atom on the chloromethane isn't bonded to a highly electronegative atom ( eg. Nitrogen, oxygen or fluorine)

But only polar molecules have pdpd?
So how would you know that they're polar.

You can tell if a molecule is polar if there is an unequal share of electrons due to a more electronegative element present, which causes one end to be slightly positive and one end to be slightly negative. However the molecule is only polar if the centre of positivity and centre of negativity are not in the same place.
Are you doing f332 next week?
