The water layer was drained into the beaker labeled water layer. Of course, if you are confident that you had utilized sufficient concentration then there may be another reason for the decreased intensity. B | Ethyl Benzoate | Alcohol, Grignard Reaction: Synthesis of Triphenylmethanol Carbon dioxide reacts with the Grignard reagent especially. Figure 2a shows a broad peak at ~3,200 -3,500 cm-1. The bromobenzene was first transformed into the Grignard compound and was then reacted with the benzophenone to make the final product.
