JEE PYQ: Coordination Compounds Question 14
Question 14 - 2020 (02 Sep Shift 1)
For octahedral Mn(II) and tetrahedral Ni(II) complexes, consider the following statements:
(I) both the complexes can be high spin. (II) Ni(II) complex can very rarely below spin. (III) with strong field ligands, Mn(II) complexes can be low spin. (IV) aqueous solution of Mn(II) ions is yellow in color.
The correct statements are:
(a) (I) and (II) only (b) (I), (III) and (IV) only (c) (I), (II) and (III) only (d) (II), (III) and (IV) only
Show Answer
Answer: (c)
Solution
Mn(II) is light pink in aqueous solution (not yellow), so (IV) is incorrect. Statements (I), (II), and (III) are correct.
