Question

Assertion: In Baeyer’s oxidation of ethene ${SP}^2$ carbon is changed to ${SP}^3$ carbon.

Reason: Cold dil. alk. ${KMnO}_4$ is Baeyer’s reagent.

• A. Both Assertion and Reason are correct, Reason is the correct explanation of Assertion
• B. Both Assertion & Reason are correct, Reason is not the correct explanation of Assertion
• C. Assertion is true but Reason is false
• D. Assertion is false but reason is true

Answer 1

Answer: (B)

Both Assertion & Reason are correct, Reason is not the correct explanation of Assertion

Alkaline $KMn{O}_4$ is known as Baeyer's reagent. When alkene reacts with dil. alkaline $KMn{O}_4$, glycol (dihydroxy) compunds are formed; as in this process we get saturated product from unsaturated reactant. So hybridization of ethene carbon changes from $s{p}^{2}tos{p}^3$.
