Question

The paramagnetic species among the following is/are (Given: Atomic numbers of Cr = 24; Fe = 26; Ni = 28):

• A. [Fe(CN)\(_6\)]\(^{3-}\)
• B. [Ni(OH\(_2\))\(_6\)]\(^{2+}\)
• C. [Ni(CN)\(_4\)]\(^{2-}\)
• D. [Cr(CN)\(_6\)]\(^{3-}\)

Answer 1

The Correct Option is A, B, D

The correct options are (A):[Fe(CN)\(_6\)]\(^{3-}\),(B): [Ni(OH\(_2\))\(_6\)]\(^{2+}\) ,(D): [Cr(CN)\(_6\)]\(^{3-}\)
