Statement 1: The lowest oxide of a transition metal (say, chromium, atomic number 24) is basic whereas the highest oxide is usually acidic. Statement 2: Cr2O3 is amphoteric in nature

Question

Statement 1: The lowest oxide of a transition metal (say, chromium, atomic number 24) is basic whereas the highest oxide is usually acidic. Statement 2: Cr2O3 is amphoteric in nature (A) If both Statement 1 and Statement 2 are true and the statement 2 is the correct explanation o f the statement 1. (B) If both Statement 1 and Statement 2 are true but statement 2 is not the correct explanation o f the statement 1. (C) If Statement 1 is true but Statement 2 is false. (D) If Statement 1 is false but Statement 2 is true

Both are correct statements but statement 2 is not correct explanation of statement 1. As the oxidation states of metals increase, the electronegativity values also increase. As a result the difference of electronegativities between metal and oxygen decreases and, therefore, acidic character of oxides increase.
