The correct answer is B.
Statement I:
cis-2-Butene on reaction with cold dilute KMnO4,
the solution produces meso2,3butanediol.
It is a dihydroxylation reaction and two -OH groups are added across the C=C bond.
cis-2-Butene on reaction with cold dilute KMnO4,
the solution produces meso2,3butanediol.
It is a dihydroxylation reaction and two -OH groups are added across the C=C bond.
Statement II:
2KMnO4 + H2O + KI → 2MnO2 + 2KOH + KIO3
I + 6OH−→ IO3− + 3H2O + 6e−
When alkaline KMnO4 is treated with KI, I−
is oxidised to IO3−
But, Statement II is not the correct explanation of Statement I.

Statement I: cis-2-butene with cold, dilute, alkaline KMnO4 gives meso-2,3-butanediol.
Statement II: In alkaline solution, under cold conditions, KMnO4 acts as a mild oxidizing agent.
Let's analyze each statement separately:
Statement I:
cis-2-butene is an alkene with a double bond between the second and third carbon atoms.
KMnO4 is a strong oxidizing agent that can oxidize alkenes.
When cis-2-butene reacts with cold, dilute, alkaline KMnO4, it results in the formation of meso-2,3-butanediol.
Explanation:
Meso-2,3-butanediol is a compound that contains two hydroxyl groups (-OH) attached to the second and third carbon atoms of the butane molecule. The reaction between cis-2-butene and KMnO4 in alkaline solution leads to the formation of this compound.
Statement II:
KMnO4 acts as a mild oxidizing agent in alkaline solution under cold conditions.
Explanation:
KMnO4 is a strong oxidizing agent that can oxidize various organic compounds. However, under cold conditions and in an alkaline solution, the reactivity of KMnO4 is reduced, and it acts as a mild oxidizing agent. This means that it can selectively oxidize certain functional groups or compounds without causing excessive oxidation.
In the given statement, KMnO4 in alkaline solution under cold conditions is used to oxidize cis-2-butene to form meso-2,3-butanediol. The reaction conditions ensure that the oxidation is mild and selective, resulting in the desired product.
Conclusion:
Both Statement I and Statement II are correct. Statement II provides a correct explanation for Statement I. The reaction between cis-2-butene and cold, dilute, alkaline KMnO4 yields meso-2,3-butanediol, and this reaction occurs because KMnO4 acts as a mild oxidizing agent under those specific conditions.
Statement II: In alkaline solution, under cold conditions, KMnO4 acts as a mild oxidizing agent.
