Question: What type of intermolecular force is present in H2O?

Options:

  1. London dispersion forces
  2. Dipole-dipole interactions
  3. Hydrogen bonding
  4. Ionic interactions

Correct Answer: Hydrogen bonding

Solution:

H2O exhibits hydrogen bonding due to the presence of hydrogen atoms bonded to highly electronegative oxygen.

Questions & Step-by-Step Solutions

What type of intermolecular force is present in H2O?
  • Step 1: Identify the chemical formula H2O, which represents water.
  • Step 2: Recognize that H2O consists of two hydrogen (H) atoms and one oxygen (O) atom.
  • Step 3: Understand that oxygen is highly electronegative, meaning it attracts electrons more strongly than hydrogen.
  • Step 4: Note that the difference in electronegativity between hydrogen and oxygen creates a polar bond, where oxygen has a partial negative charge and hydrogen has a partial positive charge.
  • Step 5: Realize that the partial positive charge of hydrogen can attract the partial negative charge of oxygen in nearby water molecules.
  • Step 6: Conclude that this attraction between hydrogen atoms of one water molecule and the oxygen atom of another water molecule is called hydrogen bonding.
