Q1.What are the rules for finding oxidation states? Q2.In bleaching powder (CaOCl2), the oxidation state of the two chlorine atoms is 0, + 1 + 1, + 2 0, – 1 –1, + 1 Q3.Why does fluorine show a negative oxidation state only?
The oxidation-state change definition is usually compatible with the above rules for applying the oxygen-atom-transfer and hydrogen-atom-transfer criteria and always compatible with the electron-transfer criterion when it is applicable. The oxidation state of any atom is indicated by a roman numeral...
The redox behavior of conjugated polymers is very important for applications to optoelectronic devices because the conductivity of conjugated polymers can be increased from an insulator level to a conductor level by doping, and various physicochemical properties such as color can be changed. There are ...
