Which of the following pairs of molecules form hydrogen bonds?
-
C\(_{2}\)H\(_{5}\)OH and CH\(_{3}\)OH
- CH\(_{3}\)OH and H\(_{2}\)
- H\(_{2}\)S and CH\(_{4}\)
- NH\(_{3}\) and SO\(_{2}\)
The correct answer is: A
Explanation
In alcohols the hydrogen bond is formed due to the covalent bonds between one oxygen atom and one hydrogen atom in the hydroxyl group (O—H).
