Question

Methanol And Ethanol Are Miscible In Water Due To

• A. Covalent Character
• B. Oxygen Bonding Character
• C. Hydrogen Bonding Character
• D. None Of These.

Answer 1

The correct option is C

Hydrogen Bonding Character

The explanation for Correct answer:

Option C Hydrogen Bonding Character

• Methanol and Ethanol are miscible with water even though these organic molecules
• In the two organic molecules methanol and ethanol, the alcoholic group$(-\mathrm{OH})$ is present.
• This alcoholic group is responsible for the formation of a Hydrogen-bonded structure with water.
• The $\mathrm{O}$ atoms present in the water and alcoholic compounds can form a Hydrogen bond with the $\mathrm{H}$ atoms.
• This Hydrogen bonding character helps in the bonded structure in the proper mixing of the molecules in the given solution.
• Hence option C Hydrogen Bonding Character is correct.

The explanation for incorrect answer:

Option A Covalent Character

• The Hydrogen bonding helps in the proper mixing of the Methanol and Ethanol in the given solution.
• The polar covalent bond $\mathrm{O}-\mathrm{H}$ present in these alcoholic groups is responsible for the formation of these interactions.
• This $\mathrm{O}-\mathrm{H}$ polar molecule mix with water by forming a miscible mixture of the alcoholic chemicals in the water.
• Hence option A Covalent Character is incorrect.

Option B Oxygen Bonding Character

• The $\mathrm{O}$ atoms present in the water and alcoholic compounds will form a Hydrogen bond with the $\mathrm{H}$ atoms.
• This Hydrogen bonding will help in the proper mixing of the molecules in the given solution.
• Hence Option B Oxygen Bonding Character is incorrect.

Option D None Of These

• Option A Hydrogen Bonding Character is correct.
• Hence Option D None of these is incorrect.
