**Question:**

What are the intermolecular forces of 1,3-diphenyl-2-propyn-1-one?

---

**Answer:**

Intermolecular forces in 1,3-diphenyl-2-propyn-1-one include:

1. **London Dispersion Forces:** Present in all molecules, these are weak interactions due to temporary dipoles in the electron cloud.

2. **Dipole-Dipole Interactions:** Arising from the polar carbonyl group (C=O), where there is a partial negative charge on the oxygen and partial positive on the carbon.

3. **π-π Interactions:** Due to the aromatic phenyl rings, which can engage in stacking interactions with each other.

These forces contribute to the molecule's physical properties, such as boiling and melting points, solubility, and volatility.
