Which of the following statements about H2S is false?
Correct answer: D. It is a weak base in water
- A. It is a covalent compound
- B. It is a gas with bad smell
- C. It is a stronger reducing agent than H2O
- D. It is a weak base in water
Explanation
H2S acts as weak acid in water, not as a weak base. In H2S, the influence of the nucleus is less and hence, it can give away its electrons.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
