Compounds of alkaline earth metals are less soluble in water than the corresponding alkali metal salts due to:

A

Their high ionisation energy

B

Their low electronegativity

C

Their low hydration energy

D

Their high lattice energy

Text Solution

Verified by Experts

The correct Answer is:
D
Along the period atomic size decreases and nuclear charge increases and thus lattice energy increases.
Lattice enegy `prop("Change on cation")/("Size of cation")`
