**Question:**

Which of the following compounds exhibits primarily dipole-dipole intermolecular forces?

- F₂
- CO₂
- CH₃-O-CH₃
- CH₃Cl

**Answer Explanation:**

When determining which compound exhibits dipole-dipole intermolecular forces, it's important to understand that such forces occur in polar molecules where there is an uneven distribution of electron density. This uneven distribution creates a dipole, consisting of a partial positive and a partial negative charge. Compounds like F₂ and CO₂ are nonpolar and do not exhibit dipole-dipole forces. CH₃-O-CH₃ (dimethyl ether) and CH₃Cl (methyl chloride) are polar compounds, but CH₃Cl is more typical for primarily exhibiting dipole-dipole forces due to its permanent dipole and higher polarity compared to CH₃-O-CH₃.

**Note:** The response involves an educational explanation suitable for a learning environment, focusing on the concept of intermolecular forces.

Expert Solution
Step 1 Theory

London forces: This intermolecular force exist in non-polar compounds. 

Dipole-dipole forces: This intermolecular force exist in polar molecules. 

Polar molecules are formed by atoms having large difference in their electronegativity.

Non-polar molecules are formed by atoms of same or nearly same electronegativity.
