Question

Match Column-I with Column-II: \[ \begin{array}{ll} \textbf{Column-I} & \textbf{Column-II}\\ A.\ \text{Homoleptic} & I.\ \text{Complex containing different ligands}\\ B.\ \text{Heteroleptic} & II.\ \text{Ligand having two donor atoms}\\ C.\ \text{Hexadentate} & III.\ \text{Complex containing only one type of ligand}\\ D.\ \text{Bidentate} & IV.\ \text{Ligand having six donor atoms} \end{array} \]

• A. A-III, B-I, C-II, D-IV
• B. A-I, B-III, C-IV, D-II
• C. A-II, B-IV, C-I, D-III
• D. A-III, B-II, C-I, D-IV

Hint:

Remember the following definitions: \[ \boxed{ \begin{aligned} \text{Homoleptic} &\rightarrow \text{One type of ligand}\\ \text{Heteroleptic} &\rightarrow \text{Different ligands}\\ \text{Bidentate} &\rightarrow \text{Two donor atoms}\\ \text{Hexadentate} &\rightarrow \text{Six donor atoms (EDTA)} \end{aligned} } \] These definitions are frequently tested in Coordination Chemistry.

Answer 1

The Correct Option is A

Organic reactions are classified by mechanism and bond changes: addition reactions add atoms or groups across a multiple bond; substitution reactions replace one atom or group with another while keeping the carbon count; elimination reactions remove atoms or groups to form a new pi bond. Each example in the column is matched to its reaction type based on these criteria.
