Question

your group is given a colorless liquid unknown. you measure its boiling point and find it to be 82°c. based on the boiling points provided below, which of the following could be the identity of your unknown?

• acetone: 56°c
• ethanol: 78°c
• tert - butanol: 82°c
• 2 - propanol: 82°c
• water: 100°c

select one:
o tert - butanol or 2 - propanol
o acetone
o water
o ethanol

Explanation:

The boiling point of the unknown liquid is \(82^{\circ}C\). Among the given options, 2 - propanol has a boiling point of \(82^{\circ}C\) and tert - butanol also has a boiling point of \(82^{\circ}C\).

Answer:

ter - butanol or 2 - propanol
