Question

Among these Cl-containing chemicals, which one has the lowest oxidation state of Cl? O CIF3 OHCIO2 OHClO3 OCIO OHCI

Answer 1

aj clF3 = → Rules to find the oxidation state! " Free element have Oxidation numbez zelo 3 neukdal compound all oxidation numbez add up to zero 3) in ion, the charges are added in Oos. 4 alkali mekts have oxidation numbed = +1 S] Alkaline earth metals = +2 Gi Hydrogen with metals 7 Hydrogen with Non-metals = +1 of oxygen cexcept in H2O2) =-2 qj Halogens (F, cl, 32,1) a → Neutral compound = consider Oxidation State Of Clis ac → Fhas -1 oxidation Slate 2C+36-1)=0 C-3 X =+3 CIFB 11

OS. Of clin clf3 = +3 2) Holo2 : Let O-SOFCI 20 => Hydrogen has +1 Os attached to non-metais) → oxygen has -2 OS - +1 + 2 + 2C-2) = 0 +1 +X-4 X-3 X = +3 :: O.S of er in Helą is =+3 3) HCIO3 :. Let O-S OF Cl = 0 +1+2+ 3(-2) = 0 + 1 + 20-G . -5=0 DC=+S : O.S OF clin Holm is +5 41 cio :. Letos Of Cl = 20 20-25-1 22-1+2 - 2-t! :.O.S OF CI in cioe is +1 5 Hel Leto-Sofel = 20 +1+X=0 Cs-1 of clin Hel = -1 : Hel has-1 oxidation state. Hence it has lowest oxidat Lion state of cl
