My favorite branch is the organic chemistry laboratory 1 since it is done on par with organic chemistry 1 so the practical classes are immediately complemented with the same laboratory. This branch is based mainly on the synthesis of organic compounds, we must also analyze the product that we synthesize through thin-layer chromatography (TLC) to see if the synthesized product differs from the precursor, on the other hand we calculate the melting point and boiling to verify the purity of the compound. I like it since they are very chemical theoretically practical then all our knowledge is reflected in each flask we use. Since it is a laboratory without a chair, the classes turn out to be 100% practical, this branch belongs to the department of organic chemistry and physical chemistry and is under the responsibility of Professor Vicente Castillo. We are 32 people and within them are two of my best friends at the university so the classes are very pleasant to share even if they are 2 min with them as future colleagues. This branch is very important in the basis for future chemicals since it represents an area that covers many research topics.
