Which factors determine the percentage yield in a laboratory preparation?
Experimental preparations of compounds usually follow the standard methodology, i.e. 1. reaction 2. work-up 3. purification The theoretical yield can be simply calculated froma knowledge of the stoichiometry of the reaction(s) involved in the preparation. The final percentage yield is calculated from actual yield/theoretical yield x 100% For example In the preparation of nitrobenzene by…
