In MgCl2, the oxidation state of ‘Cl’ is :
- A
0
- B
+2
- C
-2
- D
-1
In MgCl2, the oxidation state of Mg is +2 since it is a Group 2 element and tends to lose two electrons to attain a noble gas configuration. Since MgCl2 is a neutral compound, the sum of the oxidation states of all the atoms in the compound should be zero.
Let the oxidation state of Cl be x. Since there are two Cl atoms, the total contribution of Cl to the oxidation state will be 2x. Therefore, we can write:
+2 + 2x = 0
Solving for x, we get:
x = -1
Thus, the oxidation state of Cl in MgCl2 is -1.
Incorrect. Chlorine usually has an oxidation state of -1 in compounds, except when it is bonded to oxygen or fluorine.
Incorrect. A positive oxidation state for chlorine is uncommon. Chlorine is more electronegative than magnesium and will not have a positive oxidation state in this compound.
Incorrect. Chlorine typically has an oxidation state of -1 in compounds, especially when paired with less electronegative elements like magnesium.
