Which one of the following is the correct definition of intramolecular forces?The forces of attraction between oppositely charged particles.The forces of electrostatic attraction that form between oppositely charged ions.The forces that hold atoms together in a molecule.The forces that are present between molecules.

The correct definition of intramolecular forces is: "The forces that hold atoms together in a molecule."

Here's why:

Intramolecular forces refer to the forces of attraction that hold the atoms together within a molecule. These forces are stronger than intermolecular forces, which are the forces that occur between molecules.

1. "The forces of attraction between oppositely charged particles." This is a general definition that could apply to many types of forces, not specifically intramolecular forces.

2. "The forces of electrostatic attraction that form between oppositely charged ions." This is a definition of ionic bonding, which is a type of intramolecular force, but not the only type. There are also covalent and metallic bonds.

3. "The forces that hold atoms together in a molecule." This is the correct definition of intramolecular forces. It includes all types of bonds (ionic, covalent, and metallic) that can occur within a molecule.

4. "The forces that are present between molecules." This is the definition of intermolecular forces, not intramolecular forces. Intermolecular forces occur between separate molecules, not within a single molecule.
