Question
The dipole-dipole interaction requires:
Correct Answer
Option D is the correct answer.
Detailed Explanation
Dipole-dipole interactions occur between polar molecules. Polar molecules have a permanent separation of charge, creating a partial positive end (δ+) and a partial negative end (δ-). These opposite partial charges attract each other.
Hint
This force exists between molecules that have a permanent dipole moment.
