1. The isotope of hydrogen used as a tracer in organic reactions is tritium (³H or T).

2. The possible isotopes of hydrogen are:
- Protium (¹H): 1 proton, 0 neutrons
- Deuterium (²H or D): 1 proton, 1 neutron
- Tritium (³H or T): 1 proton, 2 neutrons

3. Nascent hydrogen refers to hydrogen atoms that are freshly generated in situ during a chemical reaction and are highly reactive. Atomic hydrogen, on the other hand, refers to individual hydrogen atoms that are not necessarily freshly generated and may not be as reactive as nascent hydrogen.

4. Heavy hydrogen is another name for deuterium (²H or D). Two uses of heavy hydrogen are:
- As a moderator in nuclear reactors to slow down neutrons.
- In heavy water (D₂O) for various scientific and industrial applications.

5. Nascent hydrogen is a more powerful reducing agent than molecular hydrogen. This can be demonstrated by the reduction of nitrobenzene to aniline:
- Using nascent hydrogen: C₆H₅NO₂ + 6[H] → C₆H₅NH₂ + 2H₂O
- Using molecular hydrogen: C₆H₅NO₂ + 3H₂ → C₆H₅NH₂ + 2H₂O
The nascent hydrogen, being more reactive, facilitates the reduction more effectively.

6. Important uses of hydrogen as a fuel include:
- As a clean fuel in fuel cells to generate electricity, with water as the only byproduct.
- In hydrogen-powered vehicles, providing an alternative to fossil fuels and reducing greenhouse gas emissions.

7. Atomic hydrogen and nascent hydrogen:
- Atomic hydrogen consists of individual hydrogen atoms (H) and is usually generated by dissociating molecular hydrogen (H₂) at high temperatures or using an electric arc.
- Nascent hydrogen is hydrogen in its atomic form that is generated during a chemical reaction and is highly reactive due to its transient nature.
