Level 2 – Melting Point Analysis – Interpreting Results A student is in a chemistry lab and is conducting an experiment with the aid of a list of compounds to choose from, similar to what we did in our lab. A student is given a compound and must confirm its identity. They suspect it is benzoin based on its appearance, but must confirm it first. They go to the literature and note the expected melting point; then they begin to conduct a melting point experiment. The instruments and thermometer/sensor are calibrated correctly. They write in their notebook the following: “MP range average is higher than expected (+2oC compared to the ‘suspected compound’ literature value)” -and-“narrow range (1.1oC from start to finish)” What do the results of this melting point experiment most likely indicate?
