Answer 2

Answer:

Among the Ethane, Methoxy methane, Ethanol, and Ethanal, Ethanal has the highest boiling point. Hence, the correct option is (c) Ethanol.

Explanation:

As in the ethanol due to the presence of alcohol or we can say -OH group, it makes hydrogen bonding with the other -OH groups. As hydrogen bonding is the strongest bond, it requires a very high temperature to break the bond. So, the compounds having a hydrogen bond are having a high boiling point. Among Ethane, Methoxy methane, Ethanol, and Ethanal, only ethanol has hydrogen bonding.

So, Ethanol has the highest boiling point among all the four.
