Question

The INCORRECT statement is :

JEE MAIN 2019

Answer 1

$LiF$ and $L{i}_{2}O$ are comparatively much less soluble in water than the corresponding compounds of other alkali metals.

$LiCl$ is deliquescent and crystallises as a hydrate, $LiCl.2H_{2}O$ whereas other alkali metal chlorides do not form hydrates.

Lithium is least reactive but the strongest reducing agent among all the alkali metals.

$4LiN{O}_3\stackrel{\Delta }{⟶}2L{i}_{2}O+4N{O}_2\left(g\right)+O_2\left(g\right)$

So, D is the correct option.
