The incorrect statement is:
Options
- AL i N O 3 decomposes on heating to give L i N O 2 and O 2 .
- BL i C l crystallises from aqueous solution as L i C l - 2 H 2 O .
- CLithium is the strongest reducing agent among the alkali metals.
- DLithium is least reactive with water among the alkali metals.
Correct answer
A. L i N O 3 decomposes on heating to give L i N O 2 and O 2 .
Step-by-step solution
4 L i N O 3 → Δ 2 L i 2 O + 4 N O 2 g + O 2 g Due to small size of L i + 1 , its hydration energy is high and forms hydrate salt undefined
