Solution

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(-OH) is present.
  • This alcoholic group is responsible for the formation of a Hydrogen-bonded structure with water.
  • The O atoms present in the water and alcoholic compounds can form a Hydrogen bond with the 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 OH present in these alcoholic groups is responsible for the formation of these interactions.
  • This OH 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 O atoms present in the water and alcoholic compounds will form a Hydrogen bond with the 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.
