Answer:
d. Oxidation and reduction
Explanation:
For this question we have to remember the definition of each type of reaction:
-) <u>Hydrogenation</u>
<u />
In this reaction, we have the addition of hydrogen to a molecule. Usually, an alkene or alkyne. In the example, molecular hydrogen is added to a double bond to produce an alkane.
-) <u>Alkylation</u>
<u />
In this reaction, we have the addition of a chain of carbon to another molecule. In the example, an ethyl group is added to a benzene ring.
<u />
-) <u>Hydrolysis</u>
<u />
In this reaction, we have the breaking of a bond by the action of water. In the example, a water molecule can break the C-O bond in the ester molecule.
-) <u>Halogenation</u>
<u />
In this reaction, we have the addition of a halogen (atoms on the VIIIA group). In the example, "Cl" is added to the butene.
-) <u>Ammoniation</u>
<u />
In this reaction, we have the addition of the ammonium ion (). In the example, the ammonium ion is added to an acid.
-) <u>Oxidation and reduction</u>
<u />
In this reaction, we have opposite reactions. The oxidation is the loss of electrons and the reduction is the gain of electrons. For example:
Reduction
Oxidation
