Answer

To determine which compound has electrovalent, covalent, coordinate, and hydrogen bonds, we will analyze the compound given in the video transcript: Cu(H2O)4SO4·H2O.

### Step-by-Step Solution:

1. **Identify the Compound**:
The compound in question is Cu(H2O)4SO4·H2O. This compound consists of copper (Cu), sulfate (SO4), and water (H2O) molecules.

2. **Electrovalent Bond**:
- Electrovalent bonds (also known as ionic bonds) occur between metals and non-metals where there is a transfer of electrons.
- In this compound, copper (Cu) can exist in a +2 oxidation state, and sulfate (SO4) has a -2 charge. The interaction between Cu²⁺ and SO4²⁻ forms an electrovalent bond.

3. **Covalent Bond**:
- Covalent bonds are formed when two atoms share electrons.
- In Cu(H2O)4SO4·H2O, the water molecules (H2O) are coordinated to the copper ion through covalent bonds. Each water molecule shares its electrons with the copper ion.

4. **Coordinate Bond**:
- A coordinate bond (or dative bond) is a type of covalent bond where one atom provides both electrons for the bond.
- In this case, the water molecules act as Lewis bases and donate a pair of electrons to the copper ion, forming coordinate bonds.

5. **Hydrogen Bond**:
- Hydrogen bonds occur when a hydrogen atom covalently bonded to a highly electronegative atom (like oxygen) interacts with another electronegative atom.
- In the compound, the water molecules can form hydrogen bonds with each other due to the presence of hydrogen atoms bonded to oxygen.

### Conclusion:
The compound Cu(H2O)4SO4·H2O contains electrovalent bonds (between Cu²⁺ and SO4²⁻), covalent bonds (within water molecules), coordinate bonds (between Cu²⁺ and H2O), and hydrogen bonds (between water molecules).
