Functional Groups and Intermolecular Forces

The functional groups determine the reactivity of their molecules because of their ability to direct the interactions of the overall molecule. - Choose two functional groups from chapter 11 or 12. For each functional group find a household product that contains the functional groups you chose (e.g. fingernail polish remover c
