### Step-by-Step Solution:

**Step 1: Understand the definition of tranquilizers.**
- Tranquilizers are neurologically active drugs that affect the transmission of signals in the nervous system. They are commonly used to treat mental disorders, such as depression and anxiety.

**Step 2: Analyze each option.**

- **Equinil:** This is a tranquilizer used to treat anxiety and depression. It is classified as a benzodiazepine, which is known for its calming effects.

- **Analgine:** This is an analgesic drug, primarily used to relieve pain. It does not have tranquilizing properties and does not affect the nervous system in the same way as tranquilizers do.

- **Meprobamate:** This is a tranquilizer that is used to treat anxiety. It acts on the central nervous system and is known for its sedative effects.

- **Chlorodiazepoxide:** This is another tranquilizer that is used to treat anxiety and is classified as a benzodiazepine. It has sedative and anxiolytic properties.

**Step 3: Identify the option that does not act as a tranquilizer.**
- From the analysis, we can see that Analgine is the only drug that does not act as a tranquilizer. It is an analgesic and is used for pain relief.

### Final Answer:
**Analgine will not act as a tranquilizer.**
