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 high melting point
(B) Has low melting point
(C) Conducts electricity in molten state
(D) Occurs as solid
Answer.:
Compound Z is formed from a reaction between X and Y
- X loses an electron, it must be an electropositive metal .
- Y gains an electron, it must be an electronegative non-metal .
Therefore Z must be an ionic compound .
Now,
- Ionic compounds exhibit high melting and boiling points .
- They conduct electricity in their molten states .
- They generally occur in solid form.
So, the correct answer is (b)
