### Understanding Overalkylation of Ammonia

**Question: What is responsible for the overalkylation of ammonia?**

- Each alkylation produces a more resonance-stabilized amine
- Each alkylation produces a more reactive amine
- Each alkylation produces a more sterically hindered amine

In this section, users are prompted to consider the factors responsible for the overalkylation of ammonia. Overalkylation occurs when multiple alkyl groups are added to an ammonia molecule, leading to the formation of complex alkylamines.

#### Explanation of Options:
1. **Resonance Stabilization**:
   - Alkyl groups generally do not provide resonance stabilization to amines. Resonance stabilization is more relevant in systems with conjugated pi-bond systems, such as aromatic structures.
   
2. **Reactivity**:
   - Each successive alkylation can make the nitrogen in the amine more nucleophilic. This increased nucleophilicity can lead to further alkylations, facilitating the overalkylation process.

3. **Steric Hindrance**:
   - As more alkyl groups are added, the amine becomes more sterically hindered. Steric hindrance can impede further reactions, which might counteract overalkylation rather than promote it.

**Learning Note:**
The most accurate option is likely related to the increased reactivity (nucleophilicity) of the amine as it becomes more alkylated. The added alkyl groups can make the amine more reactive towards further alkylation reactions.

By understanding these concepts, students can gain a deeper insight into the underlying chemical principles governing overalkylation reactions.

### Reaction of Alkyl Halides with Ammonia

**Question:**

If a single equivalent of alkyl halides is used in a reaction with ammonia, what will be the result?

**Options:**
1. A single alkylated product
2. No reaction
3. A mixture of alkylated products

---

**Explanation:**

In organic chemistry, alkyl halides are compounds in which a halogen atom is bonded to an sp³ hybridized carbon atom. Ammonia (NH₃) is a nucleophile that can react with alkyl halides to form substituted amines through the mechanism of nucleophilic substitution. 

When a single equivalent of an alkyl halide is used in a reaction with ammonia, the primary reaction typically results in the formation of a single alkylated product. However, due to the possibility of multiple substitutions occurring, multiple alkylated products can often be produced.

**Correct Answer:**

The correct answer to the question is:
- **A mixture of alkylated products**

This is because once the first alkylation occurs, the resulting amine can further react with more alkyl halide, leading to a mix of products such as primary, secondary, tertiary amines, and possibly quaternary ammonium salts if the conditions permit.
