Sodium and potassium react with water much more vigorously than lithium because `:`

A

Sodium and potasiumhave high values of hydration energy as compared to that of lithuim.

B

Sodium and potassium have higher melting point than that of lithium.

C

Sodium and potassium have lower melting point than that of lithium.

D

Sodium and potassium have lower hydration energy than that of lithium.

Text Solution

Verified by Experts

The correct Answer is:
C
When sodium and potassium react with water the evolved causes them to melt giving a larger area of with water, lithium on the other hand, does not melt these condition and thus reacts more slowly.
