Question

Assertion : MgO exists in liquid state. Reason: The electrostatic forces of attraction between Mg2+ and 02- ions constitute ionic bond.

Answer 1

Answer:

Assertion is false and reason is true

Explanation:

MgO exists in gaseous state.

The electrostatic forces of attraction between Mg2+ and 02- ions constitute ionic bond.

Answer 2

Assertion is false but reason is true about MgO.

1. MgO is the chemical formula for magnesium oxide. It has ionic bond where sharing of two electrons takes place.
2. Ionic compounds have characteristic high melting points. This makes them solid in nature.
3. Magnesium oxide also occurs in solid form in nature.
4. Higher melting point indicates they require high temperature to melt them. Melting point of magnesium oxide is 2852° C.
