**Title: Understanding Hydrolysis of Nitriles**

**Text:**

In this transformation, the given substrate is a nitrile compound. The reaction involves the conversion of this nitrile in the presence of hydrochloric acid (HCl) at a temperature of 40°C. This is an example of an acid-catalyzed hydrolysis reaction.

**Reaction Details:**

- **Reactant:** A four-carbon nitrile (butyronitrile), characterized by the presence of a cyano group (C≡N) attached to a propyl chain.
- **Reagent:** Hydrochloric acid (HCl).
- **Conditions:** A temperature of 40°C.

**Expected Outcome:**

Under the reaction conditions, the nitrile group will undergo hydrolysis, resulting in the formation of a carboxylic acid. The major product of this reaction is likely to be butyric acid. This occurs as the nitrile group converts to a carboxyl group (-COOH) through the intermediate formation of an amide, which further hydrolyzes to the acid.

**Conclusion:**

The acid-catalyzed hydrolysis of nitriles converts them into carboxylic acids under mild temperatures and acidic conditions. This reaction pathway is crucial in organic synthesis for producing carboxylic acids from nitriles.
