12. (S)-(-)-Serine: (a) (b) (c) (d) is dextrorotatory rotates plane-polarized light in a counterclockwise direction rotates plane-polarized light in a clockwise direction is racemic
Will a 1:1 mixture of these two compounds rotate plane polarized light? 19 O A. No OB. Yes
Which of the following is FALSE regarding the optical activity? Enantiomers rotate plane polarize light to same extend, but opposite direction. 0% ee means the sample is a racemix mixture. The higher the % ee, the more enantiomerically pure the sample will be. In general, the Renantiomer will rotate plane polarize light to the right, and the S enantiomer will rotate light to the left. Aracemix mixture will have no optical rotation

3. Left circularly polarized light rotates counterclockwise viewed head on. It's complex notation is (a) By taking the real part of this expression, trace out the path of the E-vector in time. (b) This light hits a mirror placed at -0. In order to zero the component of the electric field, the outgoing wave is Notice the negative sign in front of kz, indicating the direction has reversed. In looking at this light head-on, does the light rotate clockwise or...
