Question: Which of the following will have the lowest boiling point?
Options:
0.1 M NaCl
0.1 M KBr
0.1 M MgCl2
0.1 M C6H12O6
Correct Answer: 0.1 M C6H12O6
Solution:
C6H12O6 does not dissociate, while the others do, leading to higher boiling points.

Questions & Step-by-Step Solutions
Which of the following will have the lowest boiling point?
Step 1: Understand what boiling point means. The boiling point is the temperature at which a liquid turns into a gas.
Step 2: Know that substances can have different boiling points based on their properties.
Step 3: Identify the substances in the question. One of them is C6H12O6 (glucose), and the others are likely ionic compounds or substances that dissociate in solution.
Step 4: Learn that when a substance dissociates, it breaks into smaller particles (ions), which can raise the boiling point of the solution.
Step 5: Recognize that C6H12O6 does not dissociate into ions; it stays as one whole molecule.
Step 6: Compare the substances: since C6H12O6 does not dissociate, it will have a lower boiling point compared to the others that do dissociate.
