NEET 2026 (Phase 1) · ChemistryIsomerismPrevious Year Question
Match List-I (Complex) with List-II (Type of isomerism): List-I (a) (b) (c) (d) List-II (i) Optical (ii) Solvate (iii) Geometrical (iv) Linkage Choose the correct option:
Answer: (D) (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii). \textbf{Answer:} (D) (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii).
- A.(a)-(iii), (b)-(i), (c)-(ii), (d)-(iv)
- B.(a)-(i), (b)-(iii), (c)-(ii), (d)-(iv)
- C.(a)-(ii), (b)-(iv), (c)-(iii), (d)-(i)
- D.(a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)✓
Correct Answer
(D) (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)
Solution & Explanation
\textbf{Answer:} (D) (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii). \textbf{Solution:} (a) : square-planar complex with cis and trans forms \textbf{geometrical} isomerism (iii). (b) : tris-chelate octahedral complex that is non-superimposable on its mirror image \textbf{optical} isomerism (i). (c) : the ambidentate ligand can bind through N (nitro) or O (nitrito) \textbf{linkage} isomerism (iv). (d) : water can exchange between coordination sphere and lattice \textbf{solvate (hydrate)} isomerism (ii). Thus (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii), option (D).
