Question

Use the graph below to answer the next two questions Joseph was in the lab running a new experiment measuring the vapor pressure of different substances at different temperatures Joseph forgot to label the samples he used but thought that with what he learned in chemistry he would not have to run all the experiments again. Could you help him identify which substance corresponds to the curve labeled (4)? CH_3CH_2CI CH_3CHCl_2 CH_3CH_2 CH_2CH_3 CH_3-O-CH_3 CH_3CH_2CH_3 What substance would have a boiling point of -22 degree C according to the graph above? CH_3CH_2CI CH_3CHCI_2 CH_3CH_2 CH_2CH_3 CH_3-O-CH_3 CH_3CH_2CH_3

Explanation / Answer

Part A

Propane> Butane> CH3CH2CL> CH3-O-CH3> CH3CHCl2

1>2>3>4>5. all this based on the polarity of the molecules causing ionic bond that increase the vapor pressure.

Part B) Butane
