what is the difference between coordination geometry and molecular sha...
When atoms bond to a central atom to form a molecule, they tend to do so in a way that maximizes the distance between bonding electrons. This gives the molecule a particular shape, and when no lone pairs of electrons are present, the electronic geometry is the same as the molecular shape. Things are different when a lone pair is present. A lone pair is a set of two valence electrons that aren't shared among the bonding atoms. Lone pairs occupy more space than bonding electrons, so the net effect is to bend the shape of the molecule, although the electron geometry still conforms to the predicted shape

Similar Class 12 Doubts

Read the passage given below and answer the following questions:The existence of coordination compounds with the same formula but different arrangements of the ligands was crucial in the development of coordination chemistry. Two or more compounds with the same formula but different arrangements of the atoms are called isomers. Isomers are compounds with the same molecular formula but different structural formulas and do not necessarily share similar properties. There are many different classes of isomers, like stereoisomers, enantiomers, and geometrical isomers. There are two main forms of isomerism: structural isomerism and stereoisomerism. The different chemical formulas in structural isomers are caused either by a difference in what ligands are bonded to the central atoms or how the individual ligands are bonded to the central atoms.The following questions are multiple choice questions. Choose the most appropriate answer:Q. What kind of isomerism exists between [Cr(H2O)6]Cl3 (violet) and [Cr(H2O)5Cl]Cl2.H2O (greyish green)?

Read the passage given below and answer the following questions:In ideally ionic structures, the coordination numbers of the ions are determined by electrostatic considerations. Cations surround themselves with as many anions as possible and vice versa. This maximizes the attractions between neighbouring ions of opposite charge and hence maximizes the lattice energy of the crystal. This requirement led to the formulation of the radius ratio rule for ionic structures in which the ions and the structure adopted for a particular compound depend on the relative sizes of the ions. Thus, for the stable ionic crystalline structures, there is definite radius ratio limit for a cation to fit perfectly in the lattice of anions, called radius ratio rule. This depends upon the ratio of radii of two types of ions, r+/r–.This ratio for coordination numbers 3, 4, 6 and 8 are respectively 0.155 – 0.225, 0.225 -0.414, 0.414 -0.732 and 0.732 – 1.000. The coordination number of ionic solids also depends upon temperature and pressure. On applying high pressure, coordination number increases. On the other hand, on applying high temperature, it decreases.Q.Which is not the correct statement for ionic solids in which positive and negative ions are held by strong electrostatic attractive forces?
