Which has maximum lattice energy NaCl MgCl2 CSL SrCl2?
Therefore, the inter-ionic distance between Mg²⁺ and Cl⁻ ions is shorter than that between Sr²⁺ and Cl⁻ ions, and thus the electrostatic attractive force between Mg²⁺ and Cl⁻ ions is stronger than that between Sr²⁺ and Cl⁻ ions. Hence, MgCl₂ has a greater lattice energy than SrCl₂.
What is the formula for calculating lattice energy?
Example 1: Compute the Lattice energy of NaCl by using Born-Lande equation. ro = 2.81 × 10-10 m, the sum of radii of Born-Lande equation. n = 8 the average of the values for Na+ and Cl–.
Which has a higher lattice energy MgO or MgCl2?
They will have the smallest distance between centres and will have the largest lattice energies. The smallest ions are at the top of the Periodic Table. Mg2+ is smaller than Ca2+ , so MgO has the largest lattice energy.
What is the lattice energy of SrCl2?
The values of the lattice energy for MgCl2, CaCl2, and SrCl2 are 2522 kJ/mol, 2253 kJ/mol, and 2127 kJ/mol, respectively.
Does MgCl2 have a larger lattice energy than SrCl2?
e. The values of the lattice energy for MgCl2, CaCl2, and SrCl2 are 2522 kJ/mol, 2253 kJ/mol, and 2127 kJ/mol, respectively. The difference in lattice energies between MgCl2 and CaCl2 is 269 kJ, but the difference between CaCl2 and SrCl2 is only 126 kJ/mol.
Which compounds has the smallest lattice energy NaCl or MgCl2?
In NaCl, the lattice energy related to the attractive forces between single-charged positive ions and chloride ions. In MgCl₂ or SrCl₂, the lattide energy relative to the attractive forces between doubly charged positive ions and chloride ions. Obviously, NaCl has the smallest lattice energy.
What is the lattice energy of KF?
The lattice energy of KF is 794 kJ/mol, and the interionic distance is 269 pm.
What is N in lattice energy equation?
n = Born exponent, typically a number between 5 and 12, determined experimentally by measuring the compressibility of the solid, or derived theoretically.
Which has high lattice energy NaCl or MgCl2?
U(MgCl2) = 2477; U(NaCl) = 769 kJ mol^-1 Higher lattice energy implies better stability meaning stronger bonds.
