Explanation

To solve the question of what aniline reacts with acetic anhydride to give, we can follow these steps:

### Step 1: Identify the Reactants
- **Aniline**: The chemical structure of aniline is C6H5NH2, which contains an amino group (-NH2) attached to a benzene ring.
- **Acetic Anhydride**: The chemical structure of acetic anhydride is (CH3CO)2O, which consists of two acetyl groups (CH3CO) connected by an oxygen atom.

### Step 2: Understand the Reaction Mechanism
- Aniline has a lone pair of electrons on the nitrogen atom, making it a nucleophile. Acetic anhydride has an electrophilic carbonyl carbon that can be attacked by the lone pair on the nitrogen.

### Step 3: Nucleophilic Attack
- The nitrogen atom in aniline attacks the carbonyl carbon of acetic anhydride. This leads to the formation of a tetrahedral intermediate.

### Step 4: Formation of Products
- After the nucleophilic attack, the tetrahedral intermediate collapses, resulting in the formation of an acylated product and the release of acetic acid as a by-product. The reaction can be summarized as follows:
- Aniline (C6H5NH2) + Acetic Anhydride (CH3CO)2O → Acetanilide (C6H5NHCOCH3) + Acetic Acid (CH3COOH)

### Step 5: Final Product
- The main product of the reaction is **Acetanilide (C6H5NHCOCH3)**, and the by-product is **Acetic Acid (CH3COOH)**.

### Final Answer
The reaction of aniline with acetic anhydride produces **Acetanilide and Acetic Acid**.
