JEE MAIN Chemistry QUESTION #1014
Question 1
Statement (I): An element in the extreme left of the periodic table forms acidic oxides. Statement (II): Acid is formed during the reaction between water and the oxide of a reactive element present in the extreme right of the periodic table.
  • Statement I is true but Statement II is false
  • Both Statement I and Statement II are true
  • Both Statement I and Statement II are false
  • Statement I is false but Statement II is true✔️
Correct Answer Explanation
Statement I is false — elements on the extreme left (alkali metals) form basic oxides (e.g., \(\text{Na}_2\text{O} + \text{H}_2\text{O} \to \text{NaOH}\)). Statement II is true — elements on the extreme right (halogens) form acidic oxides, e.g., \(\text{Cl}_2\text{O} + \text{H}_2\text{O} \to \text{HClO}\).
