Question

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. High melting point
• B. Low melting point
• C. Conducts electricity in molten state
• D. Occurs as solid

Answer 1

The correct option is B Low melting point

Given that the compound X and Y form compound Z.

Here, X loses electron and Y gains electron meaning that an ionic or an electrovalent bond is formed. Thus, the compound Z is a crystalline solid, has high melting and boiling point. It conducts electricity in the molten state.

The compound Z cannot have a low melting point.

Hence, the correct option is $\text{B}$
