Question: What type of intermolecular force is present in liquid water? (2021)

Options:

Correct Answer: Hydrogen bonding

Solution:

Liquid water exhibits hydrogen bonding due to the attraction between the hydrogen atoms of one water molecule and the oxygen atom of another.

What type of intermolecular force is present in liquid water? (2021)

Step 1: Understand that water is made up of molecules, each containing two hydrogen atoms and one oxygen atom (H2O).
Step 2: Recognize that the oxygen atom is more electronegative than the hydrogen atoms, meaning it attracts electrons more strongly.
Step 3: This difference in electronegativity creates a partial negative charge on the oxygen atom and a partial positive charge on the hydrogen atoms.
Step 4: When water molecules are close to each other, the positive hydrogen atoms of one molecule are attracted to the negative oxygen atom of another molecule.
Step 5: This attraction between the hydrogen of one water molecule and the oxygen of another is called hydrogen bonding.
Step 6: Conclude that the type of intermolecular force present in liquid water is hydrogen bonding.
