QNEET-2022-Ch-400: NEET 2022 Chemistry - Class 11 NEET-2022-Ch-400 Solution: Identify the incorrect statement from the following Alkali…
Identify the incorrect statement from the following Alkali metals react with water to form their hydroxides. The oxidation number of K in is +4. Ionisation enthalpy of alkali metals decreases from top to bottom in the group. Lithium is the strongest reducing agent among the alkali metals.
Multiple Choice Options
- A Alkali metals react with water to form their hydroxides.
- B The oxidation number of K in KO 2 is +4.
- C Ionisation enthalpy of alkali metals decreases from top to bottom in the group.
- D Lithium is the strongest reducing agent among the alkali metals.
Step-by-Step Verified Solution
_ Alkali metals show only '+1' oxidation state in all of their compounds.
KO 2 is a super-oxide in which O 2 _ is anion and K + is cation oxidation state of K is +1.
