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