Classification of each of each transformation as follows:
a- Oxidation
b- Reduction
c- Neither
d- Reduction
Oxidation refers to the processes where it is increases in the numbers of C-Z bond's or a decreased in the numbers of C-H bond's takes place. Z refers to elememts that are more Electronegative than the carbon atom; for example, nitrogen, oxygen, and halogens.
Reductions is a process when a decreased in the number of C-Z bond's and an increases in the numbers of C-H bonds takes places.
a- In this reactions the formation of a new C-O bond has occurred. Since oxygen is always more electronegative than the carbon, it causes a decreased in the electron's density around the carbon. Hence, oxidation always takes place in the reaction.
b-In the followings reaction, reduction takes place because of the decrease in the number of C-O bond's.
c- This reactions, there is no overall change in the number of C-H and C-O bonds. Therefore, there's is neither oxidation nor reduction taking place in the given reactions.
d-There is a decreased in the number of C-O bond's, and an increase in the numbers of C-H bond's. Therefore, reduction takes place in the reaction.
