1-propanol, 2-propanol, and 1-butanol all have boiling too close together to be separated using the simple distillation column. What equipment be used to separate a mixture of these three?
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’s compound has a melting range of 108-109 °C using 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: 111 °C Compound 2 Literature Melting point: 104 °C A) It is correct that they definitely have compound 2. B)The students have neither of the two compounds. C) The ramp rate is too high so the experimental melting range is not accurate. D) The students likely have compound 2, but should do a mixed melting range experiment with a standard of compound 2 to be certain. E) They did not separate the compounds properly, and it is still a mixture. F) The students likely have compound 1, but should do a mixed melting range…
