Which statement about coordination number of metal ion is true? a)Most...

Explanation:

The coordination number of a metal ion refers to the number of ligands that are attached to the metal atom/ion in a complex. It determines the geometry of the complex and influences its physical and chemical properties.

Statement a: Most metal ions exhibit only a single characteristic coordination number.
This statement is incorrect because different metal ions can have different coordination numbers depending on the ligands they are bonded to. For example, some metal ions can exhibit a coordination number of 4 in one complex and a coordination number of 6 in another complex.

Statement b: The coordination number is equal to the number of ligands bonded to the metal atom.
This statement is incorrect because the coordination number is not necessarily equal to the number of ligands. A coordination number refers to the total number of ligands surrounding the metal atom/ion, including both directly bonded ligands and those coordinated through bridging ligands.

Statement c: The coordination number is determined solely by the tendency to surround the metal atom with the same number of electrons as one of the rare gases.
This statement is incorrect because the coordination number is not solely determined by the tendency to surround the metal atom with the same number of electrons as one of the rare gases. While the electron configuration of a metal ion can influence its preferred coordination number, other factors such as steric effects, charge, and ligand properties also play a role.

Statement d: For most cations, the coordination number depends on the size, structure, and charge of the ligands.
This statement is correct. The coordination number of a metal ion is influenced by various factors, including the size, structure, and charge of the ligands. Larger ligands generally require a higher coordination number to accommodate them, while smaller ligands may allow for a lower coordination number. Additionally, the charge of the metal ion and the ligands can also affect the coordination number. For example, a highly charged metal ion may have a higher coordination number to balance the charges.

In summary, the coordination number of a metal ion is not fixed and can vary depending on the ligands and other factors. For most cations, the coordination number depends on the size, structure, and charge of the ligands.

Similar Class 12 Doubts

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?

Read the following text and answer the following questions on the basis of the same:Electron Microscope Electron microscopes use electrons to illuminate a sample. In Transmission Electron Microscopy (TEM), electrons pass through the sample and illuminate film or a digital camera.Resolution in microscopy is limited to about half of the wavelength of the illumination source used to image the sample. Using visible light the best resolution that can be achieved by microscopes is about ~200 nm. Louis de Broglie showed that every particle or matter propagates like a wave. The wavelength of propagating electrons at a given accelerating voltage can be determined byThus, the wavelength of electrons is calculated to be 3.88 pm when the microscope is operated at 100 keV, 2. 74 pm at 200 keV and 2.24 pm at 300 keV. However, because the velocities of electrons in an electron microscope reach about 70% the speed of light with an accelerating voltage of 200 keV, there are relativistic effects on these electrons. Due to this effect, the wavelength at 100 keV, 200 keV and 300 keV in electron microscopes is 3.70 pm, 2.51 pm and 1.96 pm, respectively.Anyhow, the wavelength of electrons is much smaller than that of photons (2.5 pm at 200 keV). Thus if electron wave is used to illuminate the sample, the resolution of an electron microscope theoretically becomes unlimited. Practically, the resolution is limited to ~0.1 nm due to the objective lens system in electron microscopes. Thus, electron microscopy can resolve subcellular structures that could not be visualized using standard fluorescences microscopy.Q.
