Given below are two statements : Statement I: The number of pairs among [Al₂O₃, Cr₂O₃] , [Cl₂O₇, Mn₂O₇] , [Na₂O, V₂O₃] and [CO, N₂O] that contain oxides of same nature (acidic, basic, neutral or amphoteric) is 4 . Statement II: Among Na₂O , Al₂O₃ , CO and Cl₂O₇ , the most basic and acidic oxides are Na₂O and Cl₂O₇ , respectively. In the light of the above statements, choose the correct answer from the options given b

Options

  1. ABoth Statement I and Statement II are true
  2. BBoth Statement I and Statement II are false
  3. CStatement I is true but Statement II is false
  4. DStatement I is false but Statement II is true

Correct answer

A. Both Statement I and Statement II are true

Step-by-step solution

Statement I: Al₂O₃ and Cr₂O₃ are both amphoteric oxides. Cl₂O₇ and Mn₂O₇ are both acidic oxides. Na₂O and V₂O₃ are both basic oxides. CO and N₂O are both neutral oxides. All 4 pairs contain oxides of the same nature. Hence, Statement I is true. Statement II: Na₂O is a strongly basic oxide. Al₂O₃ is an amphoteric oxide. CO is a neutral oxide. Cl₂O₇ is a strongly acidic oxide. Thus, the most basic oxide is Na₂O and the most acidic oxide is Cl₂O₇ . Hence, Statement II is true. Both Statement I and Statement II are tru
