When the redox reactionoccurs between the substances with different valence states, the change of thevalence state of the element must follow the law of "high price + lowprice to intermediate price". 5. Electron conservation law In any redox reaction, thetotal number of electrons obtained by an...
(na2cr2o7) acidified in dilute sulphuric acid. q2 why are tertiary alcohols not oxidised? acidified sodium or potassium dichromate(vi) solution does not oxidise tertiary alcohols. no reaction whatsoever occurs. there’s no hydrogen atom bound to the carbon in tertiary alcohols. in order to set ...
1 Oxidation and Reduction • Recall that oxidation results in an increase in the number of C—Z bonds (usually C—O bonds) or a decrease in the number of C—H bonds. • Recall that reduction results in a decrease in the number of C—Z bonds (usually C—O bonds) or an increase...
