### Acids and pKa Values

**Acetic Acid and Trifluoroacetic Acid:**

Chemical structures:
- **Acetic Acid**: H₃C—C(=O)—OH
- **Trifluoroacetic Acid**: F₃C—C(=O)—OH

The pKa of acetic acid is 4.75. 

**Question:** Which of the following statements is false?

1. The pKa of trifluoroacetic acid is larger than 4.75.
2. The conjugate base of trifluoroacetic acid is stabilized inductively.
3. The conjugate base of acetic acid is stabilized by resonance.
4. The pKa of trifluoroacetic acid is lower than 4.75.
5. The conjugate base of trifluoroacetic acid is stabilized by resonance.

### Explanation:

- **Inductive Effect**: Refers to electron withdrawing by electronegative atoms, which stabilizes the conjugate base.
- **Resonance**: Involves delocalization of electrons that stabilizes molecules.

### Practice Question for Deeper Understanding:

**Question 40:** What product(s) is/are formed in the following reaction?

*(The specific reaction is not visible in the image)*
