NDA 2026 Chemistry question
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 not correct ?
Answer: (A)
Solution
Tritium is radioactive but emits low-energy beta particles, not alpha particles, so statement I is wrong. In the gas phase the water molecule is bent, with a bond
