Answer to Question 1

3 < 4 < 2 < 5 < 1;

Criteria considered include:
1. molar mass, but in this case all were similar
2. polarity and possibility for hydrogen bonding: 3 is nonpolar; 4 is polar but cannot form hydrogen bonds; 2 is polar, but its hydrogen bonds will be weaker than those in an alcohol; 5 is a secondary alcohol, so will form fewer hydrogen bonds than its primary isomer.

Answer to Question 2

B
