>>11263377Do not listen to this until you need to learn reactions (if you ever need to.)
Review chemical properties of atoms- specifically hydrogen, oxygen, nitrogen, carbon, and halides. Review VSEPR theory, MO theory, thermodynamics, acid base (fucking HUGE, if anything make sure you know acid/base.) Be sure that you can visually picture molecules in your head on demand, and if you can’t, get a modeling kit. Unless you’re taking a lab section, throw out extraneous chemistry knowledge (limiting reagent, stoichiometry, whatever else you think chemists actually need.) That is basically it for organic chemistry 1, depending on how far you go.
