FAQs on Ace JEE Main 2025: Coordination Compounds Mock Test Practice
1. What are coordination compounds?
Coordination compounds are chemical compounds consisting of a central metal atom or ion surrounded by ligands (neutral molecules or anions) attached through coordinate bonds. These compounds often have specific three-dimensional arrangements and exhibit unique chemical properties compared to simple binary compounds.
2. How are coordination compounds named according to IUPAC rules?
The IUPAC naming of coordination compounds follows these steps:
1. Name the ligands first in alphabetical order, using appropriate prefixes (di, tri, etc.).
2. Write the name of the central metal atom/ion next.
3. Indicate the oxidation state of the metal in Roman numerals in parentheses.
4. If the compound is an anion, add the suffix "-ate" to the metal's name.
Example: [Fe(CN)6]4− is named as hexacyanoferrate(II) ion.
3. What is a ligand in coordination compounds?
Ligands are ions or neutral molecules that donate a pair of electrons to a central metal atom or ion to form a coordinate covalent bond. Common ligands include H2O, NH3, Cl-, and CN-. Ligands can be classified as monodentate (single donor atom) or polydentate (multiple donor atoms).
4. Give two examples of coordination compounds and their uses.
[Fe(CN)6]3− (Ferricyanide): Used in photography and as an analytical reagent.
[Cu(NH3)4]2+ (Tetraamminecopper(II)): Used in qualitative analysis to detect Cu2+ ions.
5. What is the difference between double salts and coordination compounds?
Double salts dissociate completely into ions when dissolved in water and lose their identity, while coordination compounds retain their complex structure and do not dissociate into simple ions in solution. For example, Potash alum is a double salt, while [Fe(CN)6]4− is a coordination compound.
6. What is the coordination number in coordination compounds?
Coordination number is the total number of ligand donor atoms directly attached to the central metal atom or ion in a coordination compound. For example, in [Co(NH3)6]3+, the coordination number of cobalt is 6.
7. Is coordination compounds an easy chapter for JEE/NEET/EAMCET?
For most students, the coordination compounds chapter is moderately easy if concepts such as nomenclature, isomerism, and bonding are clear. Regular practice of NCERT questions, previous years’ papers, and mock tests helps master this topic for exams like JEE, NEET, EAMCET, MHT-CET, and CUET.
8. How do you write the formula for a coordination compound?
Write the metal symbol first, followed by the symbols of the ligands in square brackets. Indicate the charge of the complex outside the brackets. For example:
1. [Co(NH3)5Cl]Cl2
2. [Ag(NH3)2]+
9. What types of isomerism are shown by coordination compounds?
Coordination compounds exhibit various types of isomerism: structural (linkage, ionization, coordination, hydrate) and stereoisomerism (geometrical, optical). For example, [Co(NH3)4Cl2]+ shows geometrical isomerism (cis/trans).
10. What is crystal field theory in coordination compounds?
Crystal Field Theory (CFT) explains the bonding in coordination compounds based on the interaction between metal d-orbitals and ligand electric fields. It accounts for the color, magnetism, and stability of complexes by describing how d-orbitals split into different energy levels in the presence of ligands.
11. How do coordination compounds apply in real life?
Coordination compounds are widely used in medicines (cisplatin for cancer treatment), industrial catalysis (Wilkinson's catalyst), water softening (EDTA complexes), photography, and bioinorganic processes (like hemoglobin and chlorophyll in living systems).
12. What are common mistakes to avoid while writing coordination compound formulas and names?
Common mistakes include:
1. Not arranging ligand names in alphabetical order.
2. Incorrect use of prefixes (di-, tri-) for multiple ligands.
3. Forgetting the oxidation number of the central metal.
4. Omitting square brackets for the complex ion.
5. Not using the '-ate' suffix for anionic metal complexes.
Double-check each detail to improve accuracy in exams.
