Given below are two statements :

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 oxide of a reactive element present in the extreme right of the periodic table.

In the light of the above statements, choose the correct answer from the options given below :

<p>First, let us re-state the two statements clearly:</p> <p><p><strong>Statement (I)</strong>: <em>An element in the extreme left of the periodic table forms acidic oxides.</em> </p></p> <p><p><strong>Statement (II)</strong>: <em>Acid is formed during the reaction between water and oxide of a reactive element present in the extreme right of the periodic table.</em></p></p> <hr /> <h2>Analyzing Statement (I)</h2> <p><p>The <em>extreme left</em> of the periodic table corresponds to the alkali metals (Group 1) and alkaline earth metals (Group 2). </p></p> <p><p>These metals typically form <em>basic</em> (or occasionally amphoteric, in the case of some Group 2 elements) oxides, <strong>not acidic</strong> oxides. </p></p> <p><p>For example, <strong>Na₂O</strong>, <strong>K₂O</strong>, <strong>MgO</strong>, <strong>CaO</strong>, etc., all form <em>basic</em> solutions (e.g., Na₂O + H₂O → 2 NaOH). </p></p> <p>Hence, <strong>Statement (I)</strong>—that an element in the extreme left forms acidic oxides—is <strong>false</strong>.</p> <hr /> <h2>Analyzing Statement (II)</h2> <p><p>The <em>extreme right</em> of the periodic table corresponds to the nonmetals in Groups 15, 16, 17 (and noble gases in Group 18). </p></p> <p><p>Nonmetal oxides (such as those of sulfur, phosphorus, chlorine) are generally <em>acidic</em>. </p></p> <p><p>When these oxides dissolve in water, they typically form acids. </p></p> <p><p>Example: SO₃ + H₂O → H₂SO₄ (sulfuric acid) </p></p> <p><p>Example: P₂O₅ + 3 H₂O → 2 H₃PO₄ (phosphoric acid) </p></p> <p><p>Example: Cl₂O₇ + H₂O → 2 HClO₄ (perchloric acid) </p></p> <p>Thus, <strong>Statement (II)</strong>—that acid is formed when water reacts with an oxide of a reactive element in the extreme right—is <strong>true</strong>.</p> <hr /> <h2>Conclusion</h2> <p><p><strong>Statement (I)</strong> is <strong>false</strong>.</p></p> <p><p><strong>Statement (II)</strong> is <strong>true</strong>.</p></p> <p>Therefore, the correct choice is:</p> <blockquote> <p><strong>(D) Statement (I) is false but Statement (II) is true.</strong></p> </blockquote>
