Question

Lithium is the only alkali metal which is not plced in kerosene but is wrapped in paraffin wax,beacuse

Answer 1

Explanation:

Alkali metals because of greater reactivity , placed in kerosene oil. The reactivity of group-1 elements increases from top to bottom (Li to Na).

reactivity order:Li<Na<K<Rb<Cs.

so, in alkali metals Li reactivity is some what less compared to Na, K, Rb, Cs.

so, it can be stored in paraffin wax other than kerosene oil.
