Question

Answer

Crystalline compounds are those in which particles/molecules are arranged in proper order as in ice particles/water molecules are arranged in a cage-like ordered manner so this ordered structure is called a crystalline compound.

Answer

Crystalline compounds are those which particles/molecules are arranged in proper order as in ice particles/water molecules are arranged in order like manner so it ordered structure called as crystalline compound.

Answer

Crystalline compounds are those which particles/molecules are arranged in proper order as in ice particles/water molecules are arranged in order like manner so it os called as crystalline compound.

Answer

Because in crystalline compound constitutent particles are arranged in definite repeating pattern

Answer

Becoz water form cage like structure in ordered structure due to hydrogen bonding in hydrogen atom

Answer

Introduction:
Ice is a crystalline compound because water molecules are arranged in a cage-like ordered structure. This arrangement is responsible for the unique properties of ice, including its solid-state and the ability to float on water.

Explanation:
1. Structure of Ice:
- Ice is the solid form of water, and it consists of water molecules that are arranged in a regular, repeating pattern.
- The basic building block of ice is a water molecule, which consists of two hydrogen atoms bonded to one oxygen atom.
- In the solid state, water molecules in ice are held together by hydrogen bonds.
- These hydrogen bonds are formed between the positively charged hydrogen atoms of one water molecule and the negatively charged oxygen atoms of neighboring water molecules.

2. Cage-like Structure:
- The arrangement of water molecules in ice forms a cage-like structure known as a crystal lattice.
- Each water molecule in the crystal lattice is surrounded by four neighboring water molecules, forming a tetrahedral arrangement.
- This tetrahedral arrangement creates open spaces or voids within the crystal lattice, giving ice its unique structure.
- These voids are responsible for the expansion of water when it freezes, making ice less dense than liquid water.
- The cage-like structure of ice is also responsible for its brittleness and ability to shatter when subjected to external forces.

3. Order and Stability:
- The ordered arrangement of water molecules in ice gives it a high degree of order and stability.
- This ordered structure allows ice to maintain its shape and form over time, even at low temperatures.
- The regular arrangement of water molecules also gives rise to the characteristic hexagonal shape of ice crystals.

4. Transition to Water:
- When ice is heated, the energy breaks the hydrogen bonds between water molecules, causing the crystal lattice to break down.
- This leads to the transition from the solid state to the liquid state, resulting in the formation of liquid water.
- As the crystal lattice breaks down, the ordered structure of ice is lost, and the water molecules become more randomly arranged.

Conclusion:
In conclusion, ice is a crystalline compound because water molecules are arranged in a cage-like ordered structure. This arrangement gives rise to the unique properties of ice and allows it to maintain its solid-state at low temperatures. The crystal lattice structure of ice also explains its ability to float on water and its hexagonal shape.
