A student has a mixture of two possible compounds. The student performs recrystallization to separate the two compounds. The student decides to identify the separated compound by melting point. The student observes that their isolated compound does not melt. The start temperature was 150 °C and the end temperature was 230 °C with a ramp rate of 2 °C/min. The student's partner believes that they isolated compound 2, while the student thinks they have compound 1. Choose the best answer to go with this scenario. Compound 1 Literature Melting point: 204 °C Compound 2 Literature Melting point: 188 °C
