Find oiut the oxidatoin number of chlorine in the following compunds arrange them in increasing order of oxidaiton number of chlorine NaCI_(4),NCIO_(3), NaCIO,KCIO_(3),CI_(2)O_(7),CI_(2)O,NaCI,CI_(2)CIO_(2) which oxidation state is not present in any of the above compounds

Answer»

SOLUTION :Let the O.N of CI in these compound be x
O.N of CI in `NaCIO_(4)therefore+1+x+4(-2)=0or x=+7` ltvbrgt O.N of CI in `NaCIO_(3)therefore +1 +x+3(-2)=0or x=+5`
O.N of cI in `NaCIOtherefore+1 +x+1 (-2)=0orx=+1`
O.N of CI in `NaCIO_(2)therefore+1+x+2(-2)=0 or x=+3`
P.N of CI in `CIO_(3)thereforex+3(-2)=0 or x=+6`
O.N of CI in `CI_(2)Otherefore2x+1(-2)=0or x=+1`
O.N of CI in `CI_(2)therefore2x=0or x=0`
O.N of CIin `CIO_(2)therefore2x=0 or x=0`
O.N of CI in `CIO_(2)thereforex+2 (-2)=0 or x=+4`
None of the compounds have an O.N of +2
increasing ORDER of O.N of CI is : -1,0,+1,+3,+4,+5,+6+7
