What is the formula of the hydride formed by Group 16 elements (oxygen family, valence 2)?

  1. \( \text{H}_2\text{O}, \text{H}_2\text{S}, \text{H}_2\text{Se}, \text{H}_2\text{Te} \)
  2. \( \text{NH}_3, \text{PH}_3, \text{AsH}_3 \)
  3. \( \text{HF}, \text{HCl}, \text{HBr}, \text{HI} \)
  4. \( \text{CH}_4, \text{SiH}_4, \text{GeH}_4, \text{SnH}_4 \)

Correct answer · Option 1

\( \text{H}_2\text{O}, \text{H}_2\text{S}, \text{H}_2\text{Se}, \text{H}_2\text{Te} \)

Explanation

Group 16 elements exhibit a valence of 2 and form hydrides with general formula \( \text{H}_2\text{E} \), specifically \( \text{H}_2\text{O}, \text{H}_2\text{S}, \text{H}_2\text{Se}, \text{H}_2\text{Te} \).
