Chemistry-Coordination Number
NEET Chemistry Coordination Number Match the Following Question
Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
Column-I Column-II (a) Coordination Number 4 (i) Square Planar Complex (b) Coordination Number 6 (ii) Octahedral Complex (c) Complex with unpaired electrons (iii) Paramagnetic (d) Complex with all paired electrons (iv) Diamagnetic
Choose the correct matching:
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-ii, b-iv, c-iii, d-i
D
a-iv, b-iii, c-i, d-ii
Correct Answer
Option A
Detailed Explanation
Coordination number 4 typically corresponds to square planar complexes (such as [Ni(CN)4]2–), while coordination number 6 corresponds to octahedral complexes. Diamagnetic complexes contain all paired electrons, making them distinct from paramagnetic complexes that have unpaired electrons.
