Question

Which of the following has the lowest boiling point?
Options
A CH3CH2OH
B CH3CH2CH2SH
Correct Answer
C HOCH2CH2OH
D CH3CH2CH2OH
Correct Answer

Option B is the correct answer.

Detailed Explanation

Propanethiol (CH3CH2CH2SH) has the lowest boiling point because S-H bonds form weaker hydrogen bonds than O-H bonds. Ethanol and 1-propanol have stronger hydrogen bonding, and ethylene glycol has two -OH groups for even stronger hydrogen bonding.

Hint

Which compound forms the weakest hydrogen bonds?
