How do you arrange ionic compounds in order of increasing lattice energy?
The order of increasing lattice energy is RbCl < BaS < CaO < GaP.
Which has more lattice energy LiCl or NaCl?
LiCl. Because the Li+ ion is smaller than the Na+ ion, the Coulombic attractions between ions in LiCl are stronger than in NaCl. This results in a greater lattice enthalpy.
Which has highest lattice energy LiCl NaCl KCl RbCl?
Lattice Energy
| Solid | U |
|---|---|
| LiCl | 853 |
| NaCl | 786 |
| KCl | 715 |
| MgCl2 | 2526 |
Which of the following will have high lattice energy LiCl mgcl2 NaCl CsCl?
In CsCl, there is high ionic character due to which it has high lattice energy. As a result, cesium is able to easily donate electrons to the chlorine atom which increases its ionic character.
Which ionic compounds have higher lattice energy?
The bond between ions of opposite charge is strongest when the ions are small. The lattice energies for the alkali metal halides is therefore largest for LiF and smallest for CsI, as shown in the table below. The ionic bond should also become stronger as the charge on the ions becomes larger.
How many of the following is the correct order of lattice energy?
LiF>CaF2>MgO.
Which is more stable KCl or NaCl?
Because potassium have ability to stabilize itself along with positive charge more than sodium. so KCl is more stable than NaCl. One more reason is that the atomic radius of potassium is greater than that of sodium so it can donate or lose its electron easily and becomes stable with positive charge.
Why is LiCl more soluble than NaCl?
Polarizing power for cations is very much a case of increasing with increased ion charge/ionic radius. The covalent character decreases as size of cation increases LiCl > NaCl > KCl > RbCl > CsCl. Thus LiCl is more covalent than KCl and hence KCl is more soluble in water because of decreased covalent character.
What is lattice energy of KCl?
U = -828.4 kJ/mol The lattice energy of KCl(s) is –828 kJ/mol.
Which one of the following has the highest lattice energy among LiCl Cacl2 LiF KCl?
Cacl2 should have highest Lattice enthalpy as Lattice enthalpy is directly proportional to Charge on ion and inversly propertional to size of cation and anion but Charge factors generally dominates… Both the salts have common anion Cl-.
Which has the 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 relationship between charge and lattice energy?
Lattice Energy is directly proportional to charge on cation/anion and inversely proportional to center-to-center distance of cation and anion atoms….
How does lattice energy change with increasing atomic radius?
It’s quite close to the trend of atomic radius. As atomic radius increases, i.e when you go down a column, lattice energy decreases.
How do you find the lattice enthalpy of two salts?
Lattice enthalpy of two salts can be compared by using Born–Lande equation (one of method) as, So, greater the charges of cation & anion, higher will be the lattice energy of the corresponding salt. Again, smaller the ionic radii of cation and anion, higher will be the lattice energy.
What is the lattice energy of KF and NAF?
Q. The lattice energy of KF is 794 kJ/mol, and the interionic distance is 269 pm. The Na–F distance in NaF, which has the same structure as KF, is 231… Q.
