Tag: lattice energy

From the following sequence calculate the lattice energy of AB(s):
$A(s)\rightarrow A(g)+e$;      $610\;kJ\;mol^{-1}$
$B(g)+e\rightarrow B(g);$      $-260\;kJ\;mol^{-1}$
$A(s)+B(g)\rightarrow AB(s);$      $-569\;kJ\;mol^{-1}$

The lattice energies of $KF,KCl,KBr \;$ and $\;KI$ follows the order:

Strength of ionic bond depends on lattice energy.

Identify the correct order of lattice energies.

The lattice energy of four ionic compounds $W, X, Y,$ and $Z$ are measured. The energies are found to be $-922\ kJ/mol, -769\ kJ/mol, -718\ kJ/ mol,$ and $-688\ kJ/mol$ respectively.
The four ionic, compounds are $NaCl, NaF, KBr$, and $KCl$.
Which of these ionic compounds could be identified as compound X based on the lattice energy?

Boiling point of a substance is based on the intermolecular and intramolecular forces which in turn determine the lattice energy of a substance.
Which of the following substance would have the highest boiling point?

We have all heard the phrase "opposites attract but like repels." This is especially true for ionic compounds.
Which one of the following has the largest lattice energy as a result of this attraction?

Considering only  lattice enthalpy, arrange them in the increasing order of their stability:
$NaCl$ , $MgCl _{2}$ , $MgO$

The correct order of the lattice energies of the following ionic compound is :

$MgO$ has a high melting point because due to the highly charged ions, ionic force is strong and lattice energy is........
