Which of the following pairs shows hydrogen bonding among them?
Correct answer: C. Acetone and Chloroform
- A. Ammonia and Carbon
- B. Acetone and Kerosene
- C. Acetone and Chloroform
- D. Water and Neon
Explanation
This is correct as In chloroform, three chlorine atoms are present. These atoms deprive the carbon atoms of the electrons. Due to the inductive effect, the C-H bond also becomes polar. The H- atom develops sufficient polar positive charge. Thus, a partially positively charged hydrogen atom can form a strong H-bond with an oxygen atom of acetone.

About Hydrogen Bonding
Hydrogen bonding is the strong attraction between hydrogen attached to nitrogen, oxygen or fluorine and an electronegative atom in the same or another molecule. It explains unusual boiling points, viscosity, surface tension, water's properties and the difference between intermolecular and intramolecular hydrogen bonding.
