Consider the following statements regarding the properties of hydrogen and water:
I. Tritium, the isotope of hydrogen, is radioactive and emits low energy alpha particles.
II. In the gas phase, the structure of water is linear.
III. The basic principle of a hydrogen economy is the transportation and storage of energy in the form of liquid or gaseous molecular hydrogen.
Which of the statements given above is/are correct?
I and II only
Statement I: Incorrect. Tritium (3H) is a radioactive isotope of hydrogen, but it undergoes beta decay and emits low-energy beta particles, not alpha particles.
Statement II: Incorrect. A water molecule (H2O) has a bent or V-shaped structure with a bond angle of about 104.5°. It is not linear even in the gaseous phase.
Statement III: Correct. The hydrogen economy is based on using hydrogen as an energy carrier, involving its production, storage, transportation, and utilization in gaseous or liquid form.
Therefore, Statements I and II are not correct.
Correct Answer: I and II only
