prelab wants me to draw a mechanism for both pairs. so one mechanism for the 93-95 C pair and another mechanism for the 202-204 C pair. Please draw out full mechanism with arrow pushing please for both! trans-cinnamic acid Bromination of trans-cinnamic acid can result in the formation of two different pairs of enantiomers (see Figure 4). Fortunately, the pairs of enantiomers have very different melting points. Thus, we can determine the result of this reaction by examining the melting...
