The crystals were stored to dry overnight for analysis. During the addition of sodium sulfate, the crystals clumped to the bottom and refused to form a free flowing mixture. Later when the ligroin was added, the white particles appeared nearly immediately and there was no other change to the solution through the boiling. After drying of the purified product, only The benzoic acid synthesis and purification went very smoothly.

The recovered crystals were shard-like and close to pure white. The melt temp recorded for the sample was Only Coming to the laboratory helps to reinforce these details through manually running the reaction. This lab also illustrates the variety of uses of organometallic compounds for synthesis. Grignard reagents can be used to combine whole groups of carbons, such as the benzene ring attaching to form triphenylmethanol.
