Question

The fractional distillation of a mixture of two compounds resulted in the following distillation curve. A list of possible compounds with their bp's is also shown Distillation Curve 130 120 110 100 E 80 70 60 50 40 nt (bp) ( C 56 65 69 82 98 compound boilin acetone methanol hexane 2-methyl-2-propanol 0 20 40 60 80 100 120 ane Volume (drops) toluene What is the bp of the lower-boiling compound? 65 What is the ratio of the amounts of higher-boiling to lower-boiling compounds (amt higher:amt lower - 1:1, 1:2, or 2:1)? 1:2 What is the higher-boiling compound? 98

Explanation / Answer

Lower boiling compound = hexane

BP of lower boiling compound = 69°C

Higher boiling compound = 1-butanol

BP of higher boiling compound = 117°C
