NCERT Solutions for Class 12 Chemistry Chapter 9: Points To Remember

Students can refer to the important points related to Chemistry Class 12 Class 9 mentioned below and note down the points to have a quick revision during final examinations.

  • Double Salts: These addition compounds are stable only in a solid state but lose their identity in solution form.
  • Co-ordination Compounds: These addition compounds retain their identity in a solid state as well as in solution form. In these compounds, a central atom is bonded to a number of groups through co-ordinate bonds.
  • Co-ordination Sphere: The central metal atom/ion along with ligands is written in a square bracket, [ ], called co-ordination sphere.
  • Counter Ions: The ions present outside the co-ordination sphere/entity are called counter ions.
  • Charge on Complex Ion: It is the algebraic sum of the charges on all the ligands and central atom/ion.
  • Ligands: An atom or group of atoms that can donate a pair of electrons to the central metal atom. These are of the type monodentate, bidentate, tridentate …… polydentate depending upon the number of donor sites.
  • Chelating Ligands: Multidentate ligands are chelating ligands if they can be attached to a particular metal atom simultaneously through two or more two sites.
  • Ambidentate Ligands: Unidentate ligands which have more than one donor atom through which they can co-ordinate to the central atom.
  • Co-ordination Number: The total number of ligands attached to the central metal atom in the co-ordination sphere.
  • Co-ordination polyhedron: A 3D spatial arrangement of ligands about the central atom.

FAQs on NCERT Solutions for Class 12 Chemistry Chapter 9

Q.1: What is meant by the stability of coordination compounds?

Ans: The stability of coordination compounds in a solution means the degree of association between the metal ion and the ligands involved in the state of equilibrium. Quantitatively, the strength is expressed by the equilibrium constant for the association.

Q.2: What are metal carbonyls that explain bonding in metal carbonyls?

Ans: In a metal carbonyl, the metal-carbon bond possesses both the σ and π character. The bond between the carbonyl molecule and the metal is further strengthened by the synergic effect produced by the metal-ligand bond.

Q.3: What is the importance of coordination compounds?

Ans: Coordination compounds act as industrial catalysts and are essential in many biochemical processes.

Q.4: What is the bonding in coordination compounds?

Ans: A coordination complex is a Lewis acid-base reaction product in which neutral molecules or anions (called ligands) bond to a central metal atom (or ion) by coordinating covalent bonds. Ligands are Lewis bases containing at least one pair of electrons to donate to a metal atom/ion.

Q.5: What is the fourth topic covered in Chemistry Chapter 9 syllabus of Class 12 NCERT Solutions?

Ans: The fourth topic in the Class 12 Chemistry Chapter 9 of the NCERT syllabus is Isomerism in Coordination Compounds.
