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) [Co(NH3)6]3+ (b) Coordination number 6 (ii) [Ni(CO)4] (c) Square planar geometry (iii) [Ni(CN)4]2- (d) Tetrahedral geometry (iv) [Fe(CN)6]4-
Choose the correct matching:
A
a-ii, b-i, c-iii, d-iv
B
a-iv, b-i, c-ii, d-iii
C
a-ii, b-iv, c-iii, d-i
D
a-iii, b-i, c-iv, d-ii
Correct Answer
Option A
Detailed Explanation
The coordination number is determined by the number of sigma bonds formed by ligands with the central atom. [Ni(CO)4] has a coordination number of 4 with tetrahedral geometry, while [Fe(CN)6]4- has a coordination number of 6 and octahedral geometry, matching the respective pairs in option A.
