3. Identify the functional groups present in the compound below and predict the direction of polarity in each.

**Compound:** Amphetamine

**Structure:** 
- A benzene ring is connected to a side chain.
- The side chain begins with a methylene group (CH₂) bonded to a secondary carbon (CH) which is also bonded to an isopropyl group (CH₃CHCH₃).
- An amino group (NH₂) is bonded to the same secondary carbon in the side chain.

**Functional Groups:**
- **Amino Group (NH₂):** The presence of the amino group suggests potential polar characteristics due to the difference in electronegativity between nitrogen and hydrogen, resulting in a dipole.

**Polarity:**
- The amino group contributes to the overall polarity of the molecule, as it introduces a region of partial positive and negative charges. The benzene ring itself is generally nonpolar due to its symmetrical structure and even distribution of electron density; however, the presence of the amino group can affect the molecule's interaction with polar solvents and its solubility.

When considering polarity, the NH₂ group is typically the region of higher polarity compared to the rest of the molecule due to its ability to engage in hydrogen bonding.
