Free Hydrogen Bonding MCQs with Answers
75 Hydrogen Bonding MCQs from Chemistry, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
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.

- A. 10
- B. 12
- C. 20
- D. 2
Explanation: Covalent bonds are much stronger than either, 20 times more than the H-bond and 2000 times stronger than the d-d force.
Correct answer: 20- A. Ionic bond
- B. Metallic bond
- C. H-bond
- D. None of these
Explanation: A hydrogen bond (or H-bond) is a primarily electrostatic force of attraction between a hydrogen (H) atom which is covalently bound to a…
Correct answer: H-bond- A. HCl
- B. HF
- C. HI
- D. HBr
Explanation: Due to the small size and high electronegativity of Fluorine, it does very strong Hydrogen Bonding in an HF molecule.
Correct answer: HF- A. Lower than
- B. Higher than
- C. Equal to
- D. Almost same as
Explanation: H2O have a greater boiling point than HF because H2O can form 4 hydrogen bond while HF has 2 hydrogen bond and to break all the hydrogen…
Correct answer: Lower than- A. Weaker than petrol
- B. Stronger than petrol
- C. Same as in petrol
- D. Negligible
Explanation: Melting and boiling points depend on the intermolecular strengths of a molecule, higher the boiling and melting point stronger the…
Correct answer: Stronger than petrol- A. I + IV
- B. II + IV
- C. III + IV + V
- D. I + II + III
Explanation: Hydrogen bonding is found between the hydrogen atom of one molecule (which is covalently bonded to an electronegative atom) and the…
Correct answer: III + IV + V- A. Ammonia
- B. Ethyl alcohol
- C. Carboxylic acids
- D. Hydrocarbon
Explanation: Hydrocarbons, which include alkanes, alkenes, and alkynes, do not form hydrogen bonds because they consist solely of carbon and hydrogen…
Correct answer: Hydrocarbon- A. H2O
- B. HCl
- C. CH3COOH
- D. CH3OCH3
Explanation: Due to the presence of methyl groups that bounds to oxygen there is less tendency of hydrogen bonding in ethers.Also, it does not have…
Correct answer: CH3OCH3- A. PH3
- B. CH4
- C. NH3
- D. SiH4
Explanation: Hydrogen bonding occurs when hydrogen is bonded to a highly electronegative atom such as nitrogen, oxygen, or fluorine, which creates a…
Correct answer: NH3- A. CH3
- B. CH3 OCH3
- C. CH3NH3
- D. C6 H5 OCH3
Explanation: Hydrogen bonding is possible when a hydrogen atom is bonded to another electronegative atom like O,F,N etc therefore the answer will be C.
Correct answer: CH3NH3- A. Hydrogen gas (H2)
- B. Proteins
- C. Carbohydrates
- D. Ammonia (NH3)
Explanation: Hydrogen bonding is an intermolecular force that occurs when a hydrogen atom is covalently bonded to a highly electronegative atom, such…
Correct answer: Hydrogen gas (H2)- A. CH3-O-CH3
- B. CH3 -CH2 -OH
- C. CH3 -CH2-NH2
- D. None of the above.
Explanation: Option B contains OH that can interact with the water to form a hydrogen bond with water.
Correct answer: CH3 -CH2 -OH- A. Very small size of Nitrogen
- B. Pyramidal structure of NH3
- C. Enhanced electronegative character of Nitrogen
- D. Enhanced electropositivity of nitrogen
Explanation: The boiling point of ammonia (NH3) is higher compared to the hydrides of other Group V elements because of its stronger intermolecular…
Correct answer: Enhanced electronegative character of Nitrogen- A. CH2O
- B. CH3CHO
- C. (CH3-CH2)3N
- D. All of the above
Explanation: All of them cannot form hydrogen bonds among themselves
Correct answer: All of the above- A. Acetic acid
- B. Water
- C. Ethyl alcohol
- D. Diethyl ether
Explanation: Among the options provided, water (H2O) has the highest boiling point. This is because water molecules are held together by strong…
Correct answer: Water
