**Question 3**

**Text:**

Rank the hydrogens in bold in the following molecules in order of their acidity. Rank the most acidic first down to the least acidic.

**Molecules:**

I. Acetic Acid (CH₃COOH) - Hydrogen in the hydroxyl group.

II. Pyrrolidine (C₄H₉NH) - Hydrogen attached to the nitrogen.

III. Propene (CH₃CH=CH₂) - Hydrogen on the sp² carbon.

IV. Cyclohexane (C₆H₁₀) - Hydrogen attached to a carbon.

**Ranking of Acidity:**

I > IV > II > III

**Explanation:**

This order reflects the acidity of the hydrogen atoms in each structure. Generally, hydrogens in carboxylic acids (example I) are more acidic due to resonance stabilization of the conjugate base. Hydrogens in alkanes (example IV) are less acidic as they lack resonance stabilization or significant inductive effects.
