A. is less than that of covalent bonds
B. is greater than that of covalent bonds
C. is same as that of covalent bonds
D. can be less greater or same as that of covalent bonds

Answer

To determine the length of hydrogen bonds in ice compared to covalent bonds, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Bonds in Ice**:
- Ice is composed of water molecules (H₂O) that are held together by two types of bonds: covalent bonds and hydrogen bonds.
- Covalent bonds exist within a single water molecule, where each hydrogen atom is covalently bonded to the oxygen atom.

2. **Identifying the Types of Bonds**:
- **Covalent Bonds**: These are strong bonds formed by the sharing of electrons between atoms (intra-molecular).
- **Hydrogen Bonds**: These are weaker interactions that occur between neighboring water molecules (inter-molecular) due to the attraction between the hydrogen atom of one water molecule and the oxygen atom of another.

3. **Comparing Bond Lengths**:
- The length of a bond is influenced by the strength of the bond. Covalent bonds are generally shorter and stronger than hydrogen bonds.
- In the case of ice, the covalent bonds within the water molecules pull the atoms closer together, resulting in a shorter bond length.

4. **Conclusion on Bond Lengths**:
- Since hydrogen bonds are weaker and involve interactions between separate molecules, they are longer than covalent bonds.
- Therefore, in ice, the length of hydrogen bonds is greater than that of covalent bonds.

5. **Final Answer**:
- The correct statement is: "In ice, the length of hydrogen bonds is greater than that of covalent bonds."
