Question:

The INCORRECT statement is : ALiCl crystallises from aqueous solution as LiCl.2H_2O. BLithium is least reactive with water among the alkali metals. CLithium is the strongest reducing agent among the alkali metals. DLiNO3decomposes on heating to give LiNO2andO2?

LiClcrystallises from aqueous solution asLiCl.2H2O.

Lithium is least reactive with water among the alkali metals.

Lithium is the strongest reducing agent among the alkali metals.

LiNO3decomposes on heating to giveLiNO2andO2

Solution:

Correct option is D. LiNO3 decomposes on heating to give LiNO2 and O2
2LiNO3 →Δ Li2O + 2NO2(g) + 1/2O2(g)
So, D is the correct option.
