Explanation of melting and boiling point deviations
Perfom the labs for melting pt and boiling pt on the following four and only need help with question
acetonitrile (C2H3N): GIVEN MP = -45.5C, BP = 77.3C
My results MP= -46.8 C, BP = 79.4 C
benzene (C6H6) GIVEN MP = 6.0C, BP = 80.0C
My results MP= 5.4 C BP= 82.5 C
carbon tetrachloride (CCl4):GIVEN MP = -23.0C, BP = 77.0C
My results MP=-22.3 C, BP -79.4 C
cyclohexane (C6H12): GIVEN MP = 7.0C, BP = 81.0C
My results MP= 6.5 C, BP = 82.7 C
2. For each unknown liquid, record the following:
(b) the percent deviation of each substance, given by:
percent deviation = |(measured value) - (literature value)| / |(literature value)|100%
3. Discuss the possible reasons for the discrepancies between the experimental results and the literature values
