Aniline is a weak organic base in aqueous solutions. Suggest a solvent in which aniline would become a strong base.

Answer

To solve the question of which solvent can make aniline behave as a strong base, we can follow these steps:

### Step 1: Understanding Aniline
Aniline (C6H5NH2) is a weak organic base. In aqueous solutions, it partially ionizes to form anilinium ions (C6H5NH3+) and hydroxide ions (OH-), which is why it is considered a weak base.

### Step 2: Identifying the Characteristics of a Strong Base
A strong base is one that completely dissociates in solution, producing a high concentration of hydroxide ions. Therefore, to make aniline behave as a strong base, we need a solvent that can facilitate this complete dissociation.

### Step 3: Choosing an Appropriate Solvent
A suitable solvent for aniline to act as a strong base would be a non-aqueous solvent that can stabilize the anilinium ion formed during the ionization. Solvents like **dimethyl sulfoxide (DMSO)** or **liquid ammonia** can be considered.

- **DMSO**: It is a polar aprotic solvent that can stabilize cations and anions, allowing aniline to ionize more completely.
- **Liquid Ammonia**: It is a highly polar solvent that can also stabilize the anilinium ion, promoting stronger basicity.

### Step 4: Conclusion
Thus, a solvent like **dimethyl sulfoxide (DMSO)** or **liquid ammonia** can be suggested as a medium in which aniline would behave as a strong base.
