NEET Chemistry Coordination Number Match the Following Question
Type: Match the Following-match the column-Medium-Class 12
Match Column-I with Column-II.
Column-I Column-II (a) [Ni(CN)4]2– (i) Cobalt ion surrounded by 5 ammonia molecules (b) [CoCl3(NH3)3] (ii) Square planar geometry (c) [CoCl3(NH3)5]2+ (iii) Cobalt ion surrounded by 6 groups (d) [Fe(CN)6]4– (iv) Octahedral coordination number
A
a-ii, b-iii, c-i, d-iv
B
a-i, b-ii, c-iii, d-iv
C
a-iv, b-iii, c-ii, d-i
D
a-iii, b-iv, c-i, d-ii
Correct Answer
Option A
Detailed Explanation
[Ni(CN)4]2– has a square planar geometry (ii). [CoCl3(NH3)3] corresponds to cobalt surrounded by 6 groups (iii). [CoCl3(NH3)5]2+ has a coordination number of 5 (i). [Fe(CN)6]4– is a clear example of an octahedral coordination number (iv), confirming the matches in option A.
