Expert Answer . Source(s): myself. Some anaerobic bacteria have the ability to directly convert sugar into acetic acid. The oxidation number of N in N2H4 is-2. of K is +1.Hence, the average oxidation number of I is - 1/3 However, O.N. C 6 H 12 O 6 → 2CH 3 COOH O 2 + C 2 H 4 → CH 3 COOH. The first has an oxidation number:-3, the second has an oxidation number of +3. Na2SO4. 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. (a) KI 3 In KI 3, the oxidation number (O.N.) For the perchlorate ion ClO4- , what are the oxidation states of the Cl and O, respectively? 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 Ethylene (C 2 H 4) can be oxidized into acetic acid with the help of a palladium catalyst and a heteropoly acid, as described by the following chemical reaction. In , the oxidation number of carbon of carboxylic group is -3.. Show transcribed image text. +5, - 2. CH3COOH (acetic acid) ... For the chlorate ion, ClO3- , what are the oxidation states of the Cl and O, respectively? 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. The carbon is then at the 0 (zero) oxidation state. Therefore, we will have to consider the structure of KI 3 to find the oxidation states. ) Oxygen has a -2 oxidation number 5) Group 7A elements have a -1 oxidation number 7) Group 6A elements have 2 oxidation number. O 2 + 2CH 3 CHO → 2CH 3 COOH. Question: The Second Carbon Of Acetic Acid, CH3COOH, Has An Oxidation Number Of -1 0 +1 +2 O +3. 1 0. Hence, in a KI 3 molecule, the O.N. Takker. 3. This problem has been solved! Explanation: In the given compound there are 2 carbons. cannot be fractional. ... so in ch3cooh molecle ch3 carbon have -3 and cooH carbon have +3 . OXIDATION NUMBER OF EACH ELEMENTS IN CH3COOH----O.N. In a KI 3 molecule, an atom of iodine forms a coordinate covalent bond with an iodine molecule.. In general, let's start by assuming Hydrogen will be +1 and Oxygen will be -2. of Oxygen is taken as --2 in all compounds except peroxides(-1) O.N. And carbon-carbon bond no consider because both have same electronegativity for eg in o2 molecule oxygen have zero. One carbon is attached with three hydrogen atoms, whereas the other carbon is attached with 2 oxygen atoms and one hydrogen atom. 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 . See the answer. therefore O=-2. 0 2. 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. Select the compound in which sulfur has its highest possible oxidation number. When hydrogen is combined with a non-metal then its oxidation number is +1, but in case of metals, its oxidation number is -1. Hope this helps. 8) Group 5A elements have -3 oxidation number. 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. Previous question Next question Transcribed Image Text from this Question.
