Question

How do polar molecules respond when they are placed between two metal plates, one positively charged and one negatively charged?

Answer 1

A polar molecule will have a partially positively charged end and a partially negatively charged end. The negatively charged end of the polar molecule will get attracted to the positively charged metal plate and the positively charged end of the polar molecule will get attracted to the negatively charged metal plate. This is based on Coulomb’s law of attraction of opposite charges.
