we all know that acid converts blue litmus to red on the other hand base converts red litmus paper to blue.

       According to the question the blue litmus paper does not change its colour or it stays blue that means the pH of solution is neutral or7 which prevent the colour change of the litmus paper.

Which of the following pairs of chemical reactions are inverses of each other? Answer options: a. Hydrogenation and alkylation b
mariarad [96]

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 (NH_4^+). 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:

Ag^+~+~e^-~->~Ag Reduction

Al~->~Al^+^3~+~3e^- Oxidation
