Answer

To determine which of the following substances are non-hypnotic tranquilizers, we will analyze each option based on their properties and uses.

### Step-by-Step Solution:

1. **Understanding Tranquilizers**:
- Tranquilizers are medications that help to calm the nervous system. They are primarily used to treat anxiety, stress, and related conditions.
- They can be classified into two categories: hypnotic and non-hypnotic tranquilizers. Hypnotic tranquilizers induce sleep, while non-hypnotic tranquilizers do not.

2. **Identifying Non-Hypnotic Tranquilizers**:
- **Chlordiazepoxide**: This is a medication that is used to relieve anxiety and is also helpful for individuals with alcohol dependence. It does not induce sleep, making it a non-hypnotic tranquilizer.

- **Meprobamate**: This is another tranquilizer that is commonly used for anxiety relief. It is known to slow down brain activity and promote relaxation without inducing sleep, classifying it as a non-hypnotic tranquilizer.

- **Equanil (meprobamate)**: This drug is used to treat short-term symptoms of anxiety and nervousness. It also does not have hypnotic effects, confirming its status as a non-hypnotic tranquilizer.

3. **Conclusion**:
- Since all three substances mentioned (Chlordiazepoxide, Meprobamate, and Equanil) are non-hypnotic tranquilizers, the answer to the question is that all of the above options are non-hypnotic tranquilizers.

### Final Answer:
All of the above (Chlordiazepoxide, Meprobamate, and Equanil) are non-hypnotic tranquilizers.
