**Problem 4: Proton Splitting Patterns in Compounds**

---

**Objective:**

For the compounds illustrated below, determine the expected splitting pattern for all non-equivalent protons.

---

**Chemical Structures:**

1. **Compound 1:**

   A ketone structure represented with a carbonyl group (C=O) attached to an alkyl group on one side and a methyl group (CH₃) on the other.

2. **Compound 2:**

   A straight-chain alkane displaying non-equivalent hydrogen environments due to varying lengths and branching of carbon chains.

3. **Compound 3:**

   A brominated ketone with a carbonyl group (C=O) adjacent to a tertiary butyl group and a bromo-alkyl chain, demonstrating different chemical environments for protons.

---

**Analysis:**

For each structure, identify unique sets of protons and predict their NMR splitting patterns based on neighboring protons using the n+1 rule, where n is the number of adjacent protons.
