results and main purpose provided
Introduction (6 points) (2 points each)
Discussion (30 points)(5 points each)
Schematic representation of reactions included
A clear and logical conclusion was presented and
emphasized based on analysis of all experimental data.
The conclusion was related to purpose of experiment.
Experimental melting point was explicitly compared with
literature value and product was analyzed based on this
result
Peaks in IR spectra of synthesized sulfanilamide were
explicitly compared with expected peaks for
sulfanilamide. Major peaks identified correctly.
Experimental spectra compared with literature spectra.
TLC data was analyzed and used to evaluate the identity
and purity of the sulfanilamide
Percent yield was discussed in terms of product purity.
Explanations for reported percent yield discussed.
Conclusion from Kirby Bauer Test was clearly drawn and
presented from the data collected. Activity of the
synthesized sulfanilamide analyzed in the context of
control and other antibiotics tested.
