Co-Ordination Compounds Important Questions for NEET Chemistry - 2026

Q: 2. Which subtopics from Co-Ordination Compounds should I focus on for NEET important questions?

NEET often asks about Werner’s theory, types of ligands, IUPAC naming, different isomerisms, and Crystal Field Theory basics. Prioritise magnetic and colour properties, and real-life uses in extraction and biological systems. These subtopics are main hotspots for exam-focused questions.

Q: 3. How can I quickly identify the IUPAC name of a coordination complex in NEET questions?

First, name the ligands in alphabetical order, then the central metal atom with its oxidation state shown in Roman numerals. Use prefixes (di-, tri-) for multiple same ligandsAnionic complexes end with “-ate” Practice with diverse examples for better speed.

Q: 4. What are some common assertion-reason important questions in Co-Ordination Compounds?

NEET sometimes asks assertion-reason questions on magnetic behavior (paramagnetism/diamagnetism), colour of complexes, or ligand effects on geometry. Tackle these by revising Crystal Field Theory and recognizing patterns in coordination number, hybridisation and spectral properties.

Q: 5. How do NEET examiners frame numerical and calculation-based important questions in this chapter?

Numericals usually ask for oxidation state, coordination number, total number of possible isomers, or effective atomic number (EAN). Carefully check ligand denticity and charge on each species before solving. Practicing quick calculation steps for each type will boost your accuracy.

Q: 6. What is the best strategy for revision of important questions from Co-Ordination Compounds?

Start your revision by reviewing key terms—ligands, chelation, isomerism—then solve previous-year MCQs and assertion-reason sets. Make a short error log for tricky concepts. Reviewing flashcards on IUPAC rules and isomerism can help recall them during the exam.

Q: 7. Are statement-based and match-the-following NEET questions common for this chapter?

Yes, “match the following” and statement-based questions are common exam formats for coordination compounds. They often test knowledge of examples, colour, magnetic properties, and biological importance. Practicing these will help reinforce concept links across the chapter.

1. Multiple choice questions.

Q1. Which of the following statements about coordination compounds is correct?

(a) In coordination compounds, the central atom is always a nonmetal.
(b) Ligands always donate two electrons to the metal center.
(c) Coordination number refers to the number of ligands attached directly to the central atom.
(d) Chelation always leads to a decrease in stability.

Answer: (c) Coordination number refers to the number of ligands attached directly to the central atom.

Q2. [Cr(H₂O)₆]³⁺ is an example of:

(a) Homoleptic complex
(b) Heteroleptic complex
(c) Double salt
(d) Simple salt

Answer: (a) Homoleptic complex

Q3. The IUPAC name of [Co(NH₃)₄Cl₂]Cl is:

(a) Tetraamminedichlorocobalt(II) chloride
(b) Tetraamminedichlorocobalt(III) chloride
(c) Dichlorotetraamminecobalt(III) chloride
(d) Tetraamminedichlorocobalt(I) chloride

Answer: (b) Tetraamminedichlorocobalt(III) chloride

Q4. Which ligand acts as a bidentate ligand?

(a) NH₃
(b) en (ethylenediamine)
(c) Cl^-
(d) CN^-

Answer: (b) en (ethylenediamine)

2. Very Short Answer (VSA).

Q1. Define coordination number.

Answer: Coordination number is the total number of ligand atoms directly bonded to the central metal atom in a coordination compound.

Q2. What is a chelating ligand?

Answer: A chelating ligand is a ligand that forms two or more coordinate bonds with the central metal atom through different donor atoms.

Q3. Give an example of a tridentate ligand.

Answer: Diethylenetriamine (dien) is an example of a tridentate ligand.

3. Short Answer Questions.

Q1. Explain Werner's theory of coordination compounds in short.

Answer: Werner proposed that metal ions show two types of valencies: primary (ionisable) and secondary (non-ionisable or coordination). The primary valency corresponds to oxidation state, while the secondary explains the fixed number of ligands attached to the metal ion, called the coordination number. It accounts for isomerism in such compounds.

Q2. Discuss the importance of coordination compounds in biological systems.

Answer: Coordination compounds play key roles in biological systems; for example, hemoglobin contains Fe(II) at its core forming a complex with porphyrin, transporting oxygen in blood. Similarly, chlorophyll is a magnesium coordination complex essential for photosynthesis in plants.

4. True or False Questions.

Q1. EDTA is a hexadentate ligand.

Answer: True

Q2. [Ni(CN)₄]^2– has a tetrahedral geometry.

Answer: False

Q3. Optical isomerism is possible in [Co(en)₃]³⁺.

Answer: True

3. Fill in the Blanks Questions.

Q1. The ligand which can donate more than one pair of electrons to the metal atom is called a _____________ ligand.

Answer: polydentate

Q2. The colour of coordination compounds is mainly due to _____________ transitions.

Answer: d–d
