Arrange these species in order of increasing oxidation state of chlorine. ClO2 ClO2- Cl2 Cl2O5<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/em><\/p>\n\n\n\n

To arrange these species in order of increasing oxidation state of chlorine, we need to calculate the oxidation states of chlorine in each species:<\/p>\n\n\n\n

    \n
  1. ClO2 (Chlorine dioxide):<\/strong>
    In ClO2, the oxygen atoms are more electronegative than chlorine, so oxygen is typically assigned an oxidation state of -2.
    The overall charge of the molecule is neutral, so we can assign the oxidation state of chlorine (x) as follows: x+2(\u22122)=0\u21d2x\u22124=0\u21d2x=+4x + 2(-2) = 0 \\quad \\Rightarrow \\quad x – 4 = 0 \\quad \\Rightarrow \\quad x = +4x+2(\u22122)=0\u21d2x\u22124=0\u21d2x=+4 Therefore, the oxidation state of chlorine in ClO2 is +4.<\/li>\n\n\n\n
  2. ClO2- (Chlorite ion):<\/strong>
    In ClO2-, the oxygen atoms are assigned an oxidation state of -2. Since the overall charge is -1, we can assign the oxidation state of chlorine (x) as follows: x+2(\u22122)=\u22121\u21d2x\u22124=\u22121\u21d2x=+3x + 2(-2) = -1 \\quad \\Rightarrow \\quad x – 4 = -1 \\quad \\Rightarrow \\quad x = +3x+2(\u22122)=\u22121\u21d2x\u22124=\u22121\u21d2x=+3 Therefore, the oxidation state of chlorine in ClO2- is +3.<\/li>\n\n\n\n
  3. Cl2 (Chlorine molecule):<\/strong>
    In Cl2, both chlorine atoms are in their elemental form, so their oxidation states are both 0.
    Therefore, the oxidation state of chlorine in Cl2 is 0.<\/li>\n\n\n\n
  4. Cl2O5 (Dichlorine pentoxide):<\/strong>
    In Cl2O5, the oxygen atoms are assigned an oxidation state of -2. The overall charge of the molecule is neutral. Let the oxidation state of chlorine be x. For the two chlorine atoms: 2x+5(\u22122)=0\u21d22x\u221210=0\u21d22x=10\u21d2x=+52x + 5(-2) = 0 \\quad \\Rightarrow \\quad 2x – 10 = 0 \\quad \\Rightarrow \\quad 2x = 10 \\quad \\Rightarrow \\quad x = +52x+5(\u22122)=0\u21d22x\u221210=0\u21d22x=10\u21d2x=+5 Therefore, the oxidation state of chlorine in Cl2O5 is +5.<\/li>\n<\/ol>\n\n\n\n

    Final order of increasing oxidation state of chlorine:<\/h3>\n\n\n\n

    Cl2 (0) < ClO2- (+3) < ClO2 (+4) < Cl2O5 (+5)<\/strong><\/p>\n\n\n\n

    Thus, the correct order is:Cl2<ClO2-<ClO2<Cl2O5\\text{Cl2} < \\text{ClO2-} < \\text{ClO2} < \\text{Cl2O5}Cl2<ClO2-<ClO2<Cl2O5<\/p>\n\n\n\n
