Final answer:
The boiling point and melting point, as well as the molecular weight and functional groups, are two structural features that can affect the solubility of a compound.
Step-by-step explanation:
Two obvious structural features that may affect the solubility of a compound are:
- Boiling point and melting point
- Molecular weight and functional groups
The boiling point and melting point of a compound can impact its solubility because these physical properties determine the strength of the intermolecular forces between molecules. Compounds with higher boiling and melting points tend to have stronger intermolecular forces, making them less soluble. Additionally, the molecular weight and functional groups of a compound can affect its solubility by influencing the types of intermolecular forces present. For example, compounds with polar functional groups or strong hydrogen bonding are often more soluble in polar solvents like water.
