Mendeleev's predicted formula for the oxide of Eka-silicon is \( \text{EO}_2 \). What is the formula of the chloride predicted for Eka-silicon?

  1. \( \text{E Cl}_3 \)
  2. \( \text{E Cl}_2 \)
  3. \( \text{E}_2\text{Cl}_3 \)
  4. \( \text{E Cl}_4 \)

Correct answer · Option 4

\( \text{E Cl}_4 \)

Explanation

Based on group valency, Mendeleev predicted the formula of oxide as \( \text{EO}_2 \) and chloride as \( \text{ECl}_4 \) for Eka-silicon (Germanium).
