A. Singlet oxygen is the excited state of dioxygen containing electrons paired into one of the π* orbital’s. Triplet oxygen is the ground state of dioxygen, containing two unpaired electrons in the π* orbitals. The higher energy is due to electrostatic repulsions associated with pairing the electrons in one

    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.
