Explanation: In the given compound there are 2 carbons. When hydrogen is combined with a non-metal then its oxidation number is +1, but in case of metals, its oxidation number is -1. Since the secondary alcohol on oxidation gives two different acids, acetic acid and propanoic acid, the alcohol is secondary alcohol and will contain 5 C atoms. The carbon is then at the 0 (zero) oxidation state. Therefore, by summing the product of the number of atoms and the oxidation state of each element we have +4 due to hydrogen and -4 due to oxygen. C 6 H 12 O 6 → 2CH 3 COOH CH3COOH (acetic acid) ... For the chlorate ion, ClO3- , what are the oxidation states of the Cl and O, respectively? Some anaerobic bacteria have the ability to directly convert sugar into acetic acid. Takker. of Oxygen is taken as --2 in all compounds except peroxides(-1) O.N. 8) Group 5A elements have -3 oxidation number. (a) KI 3 In KI 3, the oxidation number (O.N.) One carbon is attached with three hydrogen atoms, whereas the other carbon is attached with 2 oxygen atoms and one hydrogen atom. O 2 + 2CH 3 CHO → 2CH 3 COOH. In a KI 3 molecule, an atom of iodine forms a coordinate covalent bond with an iodine molecule.. ) Oxygen has a -2 oxidation number 5) Group 7A elements have a -1 oxidation number 7) Group 6A elements have 2 oxidation number. In general, let's start by assuming Hydrogen will be +1 and Oxygen will be -2. O 2 + C 2 H 4 → CH 3 COOH. Previous question Next question Transcribed Image Text from this Question. ... so in ch3cooh molecle ch3 carbon have -3 and cooH carbon have +3 . OXIDATION NUMBER OF EACH ELEMENTS IN CH3COOH----O.N. Therefore, we will have to consider the structure of KI 3 to find the oxidation states. Na2SO4. of Hydrogen is taken as + 1 except hydride ( - 1 ) now oxidation number of C is let x. so 2x + 2(-2) + 4(+1) =0 [ sum of ONs of all elements of neutral compound is zero] so x= 0 . This problem has been solved! Select the compound in which sulfur has its highest possible oxidation number. +5, - 2. Show transcribed image text. Source(s): myself. Hope this helps. Hence, in a KI 3 molecule, the O.N. Expert Answer . Oxygen always has oxidation number -2, except peroxide (H 2 O 2) where it is -1 and with fluorine like OF 2 it is +2. The first has an oxidation number:-3, the second has an oxidation number of +3. C H 3 C H ( O H ) C H 2 C H 2 C H 3 o x i d a t i o n , e x t r e m e c o n d i t i o n C H 3 C O O H + C H 3 C H 2 C O O H In , the oxidation number of carbon of carboxylic group is -3.. 1 0. And carbon-carbon bond no consider because both have same electronegativity for eg in o2 molecule oxygen have zero. For the perchlorate ion ClO4- , what are the oxidation states of the Cl and O, respectively? of K is +1.Hence, the average oxidation number of I is - 1/3 However, O.N. Question: The Second Carbon Of Acetic Acid, CH3COOH, Has An Oxidation Number Of -1 0 +1 +2 O +3. en there is a conflict between two of these rules or ambiguity nber, apply rule that comes first and ignore the conflicting rul What is the oxidation number for: a. CI04- b. The oxidation number of N in N2H4 is-2. See the answer. cannot be fractional. The oxidation number of oxygen is -2 and there are two oxygen atoms, so the total oxidation number for the oxygen in CO2 is -4. therefore O=-2. 0 2. 3.
