NEET Chemistry (general) 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) [Co(NH 3 ) 6 ] 3+ (i) Octahedral geometry (b) [Ni(CN) 4 ] 2- (ii) Square planar geometry (c) [Cr(en) 3 ]Cl 3 (iii) High spin complex (d) [Fe(CN) 6 ] 3- (iv) Diamagnetic behavior
Choose the correct matching:
A
a-i, b-ii, 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-iv, c-i, d-ii
Correct Answer
Option A
Detailed Explanation
[Co(NH3)6]3+ has octahedral geometry and is diamagnetic due to the absence of unpaired electrons, while [Ni(CN)4]2- is square planar. This is consistent with the information given in the NCERT text about complex geometries and their magnetic behavior.
