Results and Discussion: At the conclusion of our suction filtration, we weighed out 4.091 grams of crystals. Our percent yield was approximately 102 %. This is obviously an impossible percent yield, which suggests the presence of impurities. This is confirmed when we determined the melting point of our substance. The melting point of our product was 60- 65ºC. This was closer to methyl m-nitrobenzoate’s melting point (18 degrees below) when compared to our other choices. This inaccurate percent yield may have been caused by not maintaining a low temperature while adding the nitric/sulfuric acid mixture drop

Unformatted text preview: wise. Occasionally, we would go above the specified range. This may have resulted in our impurities in our product. Conclusion: Our experiment, despite the presence of impurities, resulted in methyl m-nitrobenzoate. Although we had an impossible percent yield and our melting point was 18 degrees below the expected range, this can be ignored because the other potential products have melting points that are farther away and this decrease is most likely due to impurities in the sample....
