The energy that opposes dissolution of a solvent is
1 Hydration energy
2 Lattice energy
3 Internal energy
4 Bond energy
Explanation:
Lattice energy opposes the dissolution of a solvent. Lattice energy is the amount of energy required to dissociate \(1\, mole\) of ionic crystal into ions.If the hydrated energy of solid is more than lattice energy, then slid dissolves.

Which of the following has highest melting point
1 \(BeC{l_2}\)
2 \(MgC{l_2}\)
3 \(CaC{l_2}\)
4 \(BaC{l_2}\)
Explanation:
(d) \(BaC{l_2}\) contain higher ionic character.

Which of the following statements is not true for ionic compounds
1 High melting point
2 Least lattice energy
3 Least solubility in organic compounds
4 Soluble in water
Explanation:
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. Therefore, leat lattice energy is not true for the ionic compounds.

Electrolytes are compound containing
1 Electrovalent bond
2 Covalent bond
3 Coordinate bond
4 Hydrogen bond
Explanation:
(a) Electrolytes are compound which get dissociated into their ion in water so it contains electrovalent bond.
