Which of the following has the lowest boiling point?
- A \(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{OH}\)
- B \(\mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{NH}_{2}\)
- C \(\mathrm{CH}_{3}-\mathrm{O}-\mathrm{CH}_{3}\)
- D \(\mathrm{HCOOH}\)
Answer & Solution
Correct Answer
(C) \(\mathrm{CH}_{3}-\mathrm{O}-\mathrm{CH}_{3}\)
Step-by-step Solution
Detailed explanation
We are given alcohol, carboxylic acid, amine and ether. So, the boiling point of ether \(\left(\mathrm{CH}_{3}-\mathrm{O}-\mathrm{CH}_{3}\right)\) will be lowest in alcohol and carboxyl acid and amines, there is H-bonding responsible for higher boiling point as compared to ether.
