Q. Identify the incorrect statement from the following

Lithium is the strongest reducing agentamong the alkali metals.

Alkali metals react with water to form their hydroxides.

The oxidation number of $K$ in $K O_{2}$ is $+ 4$ .

Ionisation enthalpy of alkali metals decreases from top to bottom in the group.

$K O_{2}$
$K^{+} O_{2}^{-} (O_{2}^{-} -$ superoxide ion $)$
