Question
**Predict the splitting pattern for each of the labeled hydrogens in the following molecules. Assume that all coupling constants are equal.**

### Molecules

#### a)
- **Structure:** 
  - A carbon backbone with a chlorine atom (Cl) attached.
  - Four labeled hydrogen atoms: 
    - \( H_a \) next to a chlorine group.
    - \( H_b \), \( H_c \), and \( H_d \) labeled around the carbon backbone.

- **Splitting Patterns:**
  - **Ha:** [Dropdown]
  - **Hb:** [Dropdown]
  - **Hc:** [Dropdown]
  - **Hd:** [Dropdown]

#### b)
- **Structure:**
  - A carbon backbone with an oxygen-linked group.
  - Four labeled hydrogen atoms:
    - \( H_a \) attached to a carbonyl group.
    - \( H_b \), \( H_c \), and \( H_d \), placed around the structure.

- **Splitting Patterns:**
  - **Ha:** [Dropdown]
  - **Hb:** [Dropdown]
  - **Hc:** [Dropdown]
  - **Hd:** [Dropdown]

### Instructions

1. **Identify** the splitting patterns for each hydrogen (Ha, Hb, Hc, Hd) in the structures provided.
2. **Select** the correct pattern from the dropdown menus for each hydrogen atom.

Note: The assumption is made that all coupling constants between hydrogens are equal. This allows simplification when predicting the NMR splitting patterns.
