and 3009.32 cm -1 and an additional stretch at 2925.11 cm -1 , indicating the presence of sp3 C-H and sp2 C-H bonds, respectively. The ketone stretch and more significantly, the C=C stretch confirms the aldol condensation occurred between the acetephenone and benzaldehyde. Interpretation of the mass spectrum gave an m/z (M+) of 252.0782 . Out of the 3 possible products, this value correlates exactly with the chalcone that had the dioxane attached. The presence of the dioxane was clearly seen in the analysis of the NMR. The multiplicities and coupling of the 1 HNMR spectrum helped confirm the structure of the product. The isolated singlet at Hydrogen i that was chemically shifted to 6.02 distinguishes how that hydrogen had to be from the dioxane, rather than the benzaldehyde with the nitro or OCH 3 group. Additionally, the integration values for the NMR add up to the 12 hydrogen’s that is present in the chalcone produced. Furthermore, the m/z provided (252.0782) completely supports how the product attained was specifically (E)-3-(1,3-benzodioxol-5- yl)-1-phenylprop-2-en-1-one. 1 Finally, the literature melting point for 3,4-methylenedioxychalcone is 113- 114°C, while the observed melting point is 116-119°C. The close resemblance assesses the purity and finalizes the identity of the product as 3,4-methylenedioxychalcone. The crude percent yield is 89.93% and the final percent yield after recrystallization is 76.64%. No side products were observed in the reaction; however, if proper methods were used, better yields would have been observed. If the experiment were to be repeated, the

    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.
