In the blanks below, type in the oxidation state of the carbon highlighted in the following oxidation reaction (make sure to include a + or - sign for positive or negative answers, i.e. +1 or -2): https://i49.tinypic.com/2cwpich.gif the oxidation state of the blue C is: the oxidation state of the red C is: hint: The oxidation state of a carbon is determined by the components bonded to it. Remember that hydrogen has an oxidation state of +1, except as H2,and oxygen has an oxidation state of -2, except when bonded to other oxygen atoms. Analyze the groups bonded to the carbon of interest. Every H contributes +1, and every oxygen contributes -2. An -OH group contributes (-2 + 1 = -1). Ignore carbons bonded to the carbon of interest. The sum of the oxidation states must be zero, since these are neutral molecules
