Can you find out why? Procedure To a 50 mL round-bottomed flask equipped with a stir bar add paraformaldehyde (0.30 g) and 95% formic acid (2 mL). Equip a condenser, stir the mixture, and heat gently using a heating mantle. After boiling for 5 min, add mesitylene (4 mL) from the top of the condenser. Reflux the mixture for 2 hours. Remove the heat and let the reaction cool to room temperature. Place the flask in an ice bath to promote crystal formation. Vacuum filter the crystals, you may need to use a spatula to break the big chunks. Rinse the flask with water (2 x 5 mL) to transfer all the solids. Wash the solids with sodium bicarbonate solution (5 mL) and then again with water (5 mL). Lastly, wash the crystals with ice-cold methanol (5 mL) to remove the unreacted mesitylene. Allow the solids to dry on your bench for 15 min. Obtain the mass and the melting point. bloid al Using a separatory funnel, separate the organic and aqueous layers and discard each in the appropriate waste container. Dimesitylmethane is a symmetric molecule and will give a simple and rather uninteresting 1H NMR. Your instructor will decide if you need to run an NMR or perform a civic engagement assignment.

3,) you have now eliminated one substitution site and should have two possible sites remaining. Provide a mechanism for the formation of each of the two remaining products. You should include all possible. Resident structures for the cat on intermediates. There should be four resident structures in each mechanism. You do not need to show the mechanism for the formation of the electrify you may assume that only a single iodine will add to the ring. a. b.
