Answer 1

Answer:

Explanation:

MgCl2 has electrovalent linkage

Answer 2

Answer:

MgCl₂ has an electrovalent linkage.

Explanation:

What is electrovalent linkage?

• A bond that exists between two oppositely charged species is called an electrovalent linkage.
• It is the force of attraction between two species.

1. CH₄: Both carbon and hydrogen are non-metals, therefore the linkage is not electrovalent.
2. SiCl₄: Both silicon and chlorine are non-metals, therefore the linkage is not electrovalent.
3. BF₃: Both boron and fluorine are non-metals, therefore the linkage is not electrovalent.
4. MgCl₂: Magnesium is a metal with a positive charge and chlorine is a non-metal with a negative charge. Therefore they are electrovalently linked.

Thus, MgCl₂ has an electrovalent linkage.
