Solution
The correct option is D Both [A] and [C].
Explanation for the correct option:
[D] Both [A] and [C].
- [A]Dihydrogen is a good reducing agent.
- This statement is wrong because Dihydrogen[] does not act as a reducing agent by itself.
- Instead, Hydrogen isotopes act as a reducing agent, reducing the metal oxides into their corresponding metals.
- But, Dihydrogen does not perform this task of reducing the substance by itself because it is unreactive.
- [C]Hydrogen has three isotopes out of which tritium is the most common.
- This statement is wrong because the Tritium isotope is the rarest occurring isotope of Hydrogen.
- It is because tritium isotope is a radioactive isotope having one electron, one proton, and two neutrons.
- So, it is very rare to occur as it occurs only through nuclear reactions in the upper atmosphere.
- So, option[D] is the correct answer.
Explanation for the incorrect options:
[A]Dihydrogen is a good reducing agent.
- It is an incorrect statement as Dihydrogen is not a good reducing agent.
- But, option[C] is also incorrect.
- So, it alone can not be the answer.
So, option[A] is incorrect.
[B] Dihydrogen does not act as a reducing agent.
- This statement is correct because Dihydrogen does not act as a reducing agent at all.
- It is because dihydrogen is unreactive as a molecule.
- So, it does not remove oxygen from the substance passed over.
- So, option B is incorrect.
[c]Hydrogen has three isotopes out of which tritium is the most common.
- It is an incorrect statement as tritium is the rarest occurring isotope due to its radioactivity and special conditions required for formation.
- But, option[A] is also incorrect.
- So, it alone can not be the answer.
- So, option[C] is incorrect.
Hence, option [D] is the correct answer. As it includes both the incorrect statements which are not true about Hydrogen.
