Compound Z is formed when X loses electrons and Y gains electrons. So, the compound Z formed is an ionic compound. And hence it shows following properties,
- High melting point
- Has high lattice energy hence mostly occur in solid state
- Has free electrons and hence conducts electricity in molten/fused state.

Understanding the Reaction Between X and Y
When elements X and Y react, they form compound Z through an electron transfer process. In this reaction, X loses an electron (oxidation) and Y gains an electron (reduction). This type of reaction typically indicates the formation of an ionic bond, where one element becomes a positively charged ion and the other becomes a negatively charged ion.
Properties of Ionic Compounds
Ionic compounds, such as the one formed by X and Y, exhibit specific properties:
- High Melting Point: Ionic compounds have strong electrostatic forces between the oppositely charged ions, resulting in high melting points.
- Conducts Electricity in Molten State: When melted, ionic compounds dissociate into their respective ions, allowing them to conduct electricity.
- Occurs as Solid: Ionic compounds are typically found as solid crystals at room temperature, due to the strong attraction between ions.
Why Z Has a Low Melting Point?
The correct answer is that Z does not exhibit a low melting point. This is because:
- Ionic compounds generally do not have low melting points. If compound Z were to have a low melting point, it would suggest a molecular or covalent structure rather than an ionic one.
- A low melting point implies weaker intermolecular forces, characteristic of covalent compounds, which do not involve the strong ionic bonds present in Z.
Conclusion
Thus, option 'B' (Has low melting point) is the correct answer, as compound Z formed from the reaction of X and Y exhibits high melting points, conducts electricity when molten, and occurs as a solid.
