Ordering the Compounds by Increasing Ionicity

To determine the order of the compounds MnCl2, FeCl2, NiCl2, and MgCl2 by increasing ionicity, we need to consider the charges of the cations and the anions in each compound.

1. MnCl2: - The cation is Mn2+ (Manganese ion) with a charge of +2. - The anion is Cl- (Chloride ion) with a charge of -1. - The compound MnCl2 consists of one Mn2+ cation and two Cl- anions.

2. FeCl2: - The cation is Fe2+ (Iron ion) with a charge of +2. - The anion is Cl- (Chloride ion) with a charge of -1. - The compound FeCl2 consists of one Fe2+ cation and two Cl- anions.

3. NiCl2: - The cation is Ni2+ (Nickel ion) with a charge of +2. - The anion is Cl- (Chloride ion) with a charge of -1. - The compound NiCl2 consists of one Ni2+ cation and two Cl- anions.

4. MgCl2: - The cation is Mg2+ (Magnesium ion) with a charge of +2. - The anion is Cl- (Chloride ion) with a charge of -1. - The compound MgCl2 consists of one Mg2+ cation and two Cl- anions.

Based on the charges of the cations and anions in each compound, we can determine the order of the compounds by increasing ionicity as follows:

FeCl2 < MnCl2 < NiCl2 < MgCl2

This means that FeCl2 has the lowest ionicity, followed by MnCl2, NiCl2, and MgCl2, with MgCl2 having the highest ionicity.

Please note that the order of the compounds by increasing ionicity is determined based on the charges of the cations and anions in each compound. Ionicity refers to the degree of ionic character in a compound, which is influenced by the difference in electronegativity between the cation and anion.
