A Chiral Compound is Optically Active If it rotates the plane clockwise = ( + ) If it rotates the place counterclockwise = ( ) A chiral compound rotates the plane of polarization of plane-polarized light .

Naming Enantiomers Assign relative priorities to the four groups. 1 = highest priority; 4 = lowest priority

Naming Enantiomers Identify chiral carbon, assign priorities 1 and 4 first. Evaluate connections for assigning priorities 2 and 3. 1 = highest priority 4 = lowest priority Prioritize Groups

    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.
