Which of the following having electrovalent covalent and co - ordinate covalent bond ?

Options

A. `BF_(3)`
B. `CuCl_(2)`
C. `CuSO_(4).5H_(2)O`
D. `FeCl_(3).H_(2)O`

Answer

To determine which of the given compounds contains electrovalent (ionic), covalent, and coordinate covalent bonds, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Identify the Bonds in Each Compound:**
- **Option A: BF3**
- Boron trifluoride (BF3) is a covalent compound. It consists of covalent bonds between boron and fluorine atoms. There are no ionic or coordinate bonds present in BF3.

- **Option B: CuCl2**
- Copper(II) chloride (CuCl2) is an ionic compound. It is formed by the transfer of electrons from copper to chlorine, resulting in the formation of Cu²⁺ and Cl⁻ ions. Therefore, CuCl2 contains electrovalent (ionic) bonds, but no covalent or coordinate covalent bonds.

- **Option C: CuSO4·5H2O**
- Copper(II) sulfate pentahydrate (CuSO4·5H2O) contains both ionic and coordinate covalent bonds. The CuSO4 part consists of ionic bonds between Cu²⁺ and SO4²⁻ ions. The five water molecules (H2O) coordinate with the copper ion, forming coordinate covalent bonds. Thus, this compound has all three types of bonds: ionic, covalent (in the water molecules), and coordinate covalent (between water and copper).

- **Option D: FCl3H2O**
- This compound is not commonly recognized, but if we consider it as a hypothetical compound, it would likely consist of covalent bonds between F and Cl. However, without specific information on the structure and bonding, it is difficult to classify it definitively. It does not appear to have ionic or coordinate covalent bonds.

2. **Conclusion:**
- Based on the analysis, the only compound that contains electrovalent, covalent, and coordinate covalent bonds is **Option C: CuSO4·5H2O**.

### Final Answer:
The compound that contains electrovalent, covalent, and coordinate covalent bonds is **CuSO4·5H2O**.
