Unformatted text preview: x Highly localized charge (+ or -) is not as stabilizing as “delocalized” charge – that is, charge spread out over more than one atom x Resonance spreads out charge distribution – this is almost always a highly stabilizing factor x The more a charge is spread out (i.e., the more resonance forms), the more stable is the ion or molecule x All resonance forms of a given molecule have the same charge x The relative positions of atoms in resonance forms do not change position (i.e., they do not move)...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
