<u>Answer:</u> The correct answer is
<u>Explanation:</u>
Oxidation number is defined as the number which is given to an atom when it looses or gains electron. When an atom looses electron, it attains a positive oxidation state. When an atom gains electron, it attains a negative oxidation state.
Oxidation state of the atoms in their elemental state is considered as 0. Hydrogen is present as gaseous state.
For the given chemical reactions:
- <u>Reaction 1:</u>
Oxidation state of hydrogen on reactant side: +1
Oxidation state of hydrogen on product side: +1
Thus, the oxidation state of hydrogen is not changing.
- <u>Reaction 2:</u>
Oxidation state of hydrogen on reactant side: +1
Oxidation state of hydrogen on product side: +1
Thus, the oxidation state of hydrogen is not changing.
- <u>Reaction 3:</u>
Oxidation state of hydrogen on reactant side: +1
Oxidation state of hydrogen on product side: +1
Thus, the oxidation state of hydrogen is not changing.
- <u>Reaction 4:</u>
Oxidation state of hydrogen on reactant side: +1
Oxidation state of hydrogen on product side: 0
Thus, the oxidation state of hydrogen is changing.
- <u>Reaction 5:</u>
Oxidation state of hydrogen on reactant side: +1
Oxidation state of hydrogen on product side: +1
Thus, the oxidation state of hydrogen is not changing.
Hence, the correct answer is
