Options

A. Electrovalent , covalent and coordinate
B. Only ionic
C. Only covalent
D. Covalent and coordinate

Answer

To determine the types of bonds present in \( NH_4Cl \) (ammonium chloride), we can analyze the components of the compound.

### Step-by-Step Solution:

1. **Identify the Components of \( NH_4Cl \)**:
- The compound consists of ammonium ion \( NH_4^+ \) and chloride ion \( Cl^- \).

2. **Determine the Bond Between \( NH_4^+ \) and \( Cl^- \)**:
- The bond between the ammonium ion and the chloride ion is an **ionic bond**. This is because \( NH_4^+ \) has a positive charge and \( Cl^- \) has a negative charge, leading to electrostatic attraction.

3. **Analyze the Structure of the Ammonium Ion \( NH_4^+ \)**:
- The ammonium ion consists of one nitrogen atom (N) covalently bonded to four hydrogen atoms (H).
- The bonds between nitrogen and hydrogen in \( NH_4^+ \) are **covalent bonds**. Each hydrogen atom shares one electron with nitrogen.

4. **Identify Any Coordinate Bonds in \( NH_4^+ \)**:
- In \( NH_4^+ \), nitrogen donates its lone pair to bond with one of the hydrogen atoms, which can be considered a **coordinate bond** (also known as a dative bond). However, in this case, since all hydrogen atoms are equivalent and nitrogen is forming four bonds, we can primarily consider them as covalent bonds.

5. **Summarize the Types of Bonds Present**:
- In \( NH_4Cl \):
- There is **one ionic bond** between \( NH_4^+ \) and \( Cl^- \).
- There are **covalent bonds** within the \( NH_4^+ \) ion.
- The bonds can also be interpreted as involving a coordinate bond due to the nature of nitrogen's bonding with hydrogen.

### Conclusion:
The types of bonds present in \( NH_4Cl \) are **ionic bonds** between \( NH_4^+ \) and \( Cl^- \), and **covalent bonds** within the \( NH_4^+ \) ion. Therefore, the correct option is **electrovalent (ionic), covalent, and coordinate**.
