# The INCORRECT statement is :

Question:

The INCORRECT statement is :

1. Lithium is least reactive with water among the alkali metals.

2. LiCl crystallises from aqueous solution as $\mathrm{LiCl} .2 \mathrm{H}_{2} \mathrm{O}$.

3. Lithium is the strongest reducing agent among the alkali metals.

4. $\mathrm{LiNO}_{3}$ decomposes on heating to give $\mathrm{LiNO}_{2}$ and $\mathrm{O}_{2}$.

Correct Option: , 4

Solution:

(4) $2 \mathrm{LiNO}_{3} \stackrel{\Delta}{\longrightarrow} \mathrm{Li}_{2} \mathrm{O}+2 \mathrm{NO}_{2}(\mathrm{~g})+\frac{1}{2} \mathrm{O}_{2}(\mathrm{~g})$
