Reaction between X and Y, forms compound Z. X loses electron and Y gains electron. Which of the following properties is not shown by Z?
(a) Has a high melting point
(b) Has a low melting point
(c) Conducts electricity in molten state
(d) Occurs as solid
Correct Answer: (b) Has low melting point
Explanation: As Z is formed when X loses an electron, and Y gains an electron. Hence, it is an ionic compound. Ionic compounds have high melting points.
