Explanation Explanation (I) (a) To determine: The definition of isomer. Isomer is basically a molecule that has same molecular formula just like another molecule, but has a different chemical structure. Isomer is basically a molecule that has same molecular formula just like another molecule, but has a different chemical structure. The number of atoms that are present in an isomer is same, but they have different connectivity. Isomers differ in physical properties like melting point, color, crystal structure and many more. For example, the cis and trans form of [ Pt ( NH 3 ) 2 ] Cl 2 (b) To determine: The definition of structural isomer. Structural isomers are basically those molecules that are of the same kind and contain the same number of atoms, but the connectivity of atoms is different. Structural isomers are basically those molecules that are of the same kind and contain the same number of atoms, but the connectivity of atoms is different. As the atoms are connected in a different manner in structural isomers, they possess different chemical behaviour. (c) To determine: The definition of stereoisomer. The isomers that consist of the same type of atoms with same type of bonds, but there is a difference in the orientation of these bonds in space. The isomers that consist of the same type of atoms with the same type of bonds, but there is a difference in the orientation of these bonds in space. Stereoisomer talks about the three dimensional arrangement of atoms. It is further of two types, one is geometrical isomer and the other is optical isomer. For example, Figure 1 (d) To determine: The definition of coordination isomer. Those isomers in which a complex ion has variation in the composition of ions are called coordination isomers. Those isomers in which a complex ion has variation in the composition of ions are called coordination isomers. The ratio between the ligands and the metal is same, with just a difference in the attachment of the ligand to the metal. For example, [ Cu ( NH 3 ) 4 ] 2 + [ ZnCl 4 ] 2 − and [ Zn ( NH 3 ) 4 ] 2 + [ CuCl 4 ] 2 − . Here in this example, the ratio of ligands and metal is same, but the ligands that are attached to the central metal atom is changed. (e) To determine: The definition of linkage isomer. The isomers in which a ligand can coordinate with metal through more than one site are called linkage isomers. Ambidentate ligands are involved in the linkage isomerism. They can coordinate with the metal through more than one site. For example, [ ( NH 3 ) 5 Co − SCN ] 2 + and [ ( NH 3 ) 5 Co − NCS ] 2 +

Coordination Chemistry

It is a part of chemistry, in which the study of compounds that have central atoms surrounded by molecules or ions, known as ligand, is known as coordination chemistry.

Question

Chapter 20, Problem 5RQ

Interpretation Introduction

Interpretation: The concept of absence of optical inactivity for a complex on the basis of presence of plane of symmetry is given. The definition of the given terms, the optical behavior of [Cr(en)2Cl2] and the presence of plane of symmetry in trans isomer and its absence in cis isomer is to be stated.

Concept introduction: The transition metal atoms have a tendency to form complex compounds that are linked to the certain neutral or ionic species and this leads to the formation of coordination compounds. There exists a large number of coordination compounds that have a large number of applications in the chemical industry as well as in daily life.
