Final answer:
H₂O (water) is the compound that exhibits dipole-dipole forces as its strongest intermolecular force among the given options. The correct answer is c.H₂O.
Step-by-step explanation:
The molecule or compound that exhibits dipole-dipole forces as its strongest intermolecular force from the given options is H₂O (water).
Water is a polar molecule due to the significant difference in electronegativity between hydrogen and oxygen atoms, creating a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom.
This leads to the dipole-dipole attraction between the positively charged end of one water molecule and the negatively charged end of another.
Other options such as BCl₃, N₂, CBr₄ are nonpolar and primarily exhibit London dispersion forces, which are weaker than dipole-dipole forces.
SO₂ is a polar molecule and also exhibits dipole-dipole interactions, but they are not stronger than those in water.
