C. Raoult's, Non-Ideal, do not, Azeotrope
D. Non-Ideal, Raoult's, Azeotrope, do not

Explanation

Let's break down the question step by step and provide the answers for each part.

### Step 1: Identify the type of solution that does not obey Raoult's law at all ranges of concentration.
- **Answer**: A solution which does not obey Raoult's law at all ranges of concentration is called a **non-ideal solution**.

### Step 2: Identify the type of solution that distills without change in composition.
- **Answer**: A solution which distills without change in composition is called an **azeotropic mixture**.

### Step 3: Identify the law that ideal solutions obey.
- **Answer**: Ideal solutions obey **Raoult's law**.

### Step 4: Identify whether ideal solutions form azeotropic mixtures.
- **Answer**: Ideal solutions do **not** form azeotropic mixtures.

### Final Answers:
1. A solution which does not obey Raoult's law at all ranges of concentration is called **non-ideal solution**.
2. A solution which distills without change in composition is called **azeotropic mixture**.
3. Ideal solutions obey **Raoult's law**.
4. They **do not** form azeotropic mixtures.
