Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
Column-I Column-II (a) MnO4– (i) Tetrahedral geometry (b) Mn2O7 (ii) Covalent nature (c) KMnO4 (iii) Dark purple crystals (d) MnO2 (iv) Ionic oxide
Choose the correct matching:
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-iii, c-i, d-iv
C
a-iii, b-iv, c-ii, d-i
D
a-iv, b-i, c-ii, d-iii
Correct Answer
Option A
Detailed Explanation
The permanganate ion (MnO4–) has a tetrahedral geometry (i), Mn2O7 is known to have covalent nature (ii), and potassium permanganate (KMnO4) forms dark purple crystals (iii). MnO2 is generally considered to be an ionic oxide (iv).
