Chemistry - ALCOHOL & ETHER Question with Solution | TestHub

Question Explanation:

Identifying the product of a poly hydroxy compound at high-temperature catalytic oxidation by Cu at $300^{\circ }\mathrm{C}$.

Concept:

This question is based on Catalytic oxidation of Alcohols by Cu at $300^{\circ }\mathrm{C}$.

Solution:

The reaction involves heating an alcohol with Cu catalyst at $300^{\circ }\mathrm{C}$. This is a classic method for the dehydrogenation of alcohols.

$1^{\circ }$ Alcohols: Oxidized to Aldehydes. The ${\mathrm{CH}}_2\mathrm{OH}$ group (on the left ring) is a $1^{\circ }$ alcohol, which converts to an - CHO .

$2^{\circ }$ Alcohols: Oxidized to Ketones. The - CHOH group (on the left ring and right ring) are $2^{\circ }$ alcohol, converted into ketone.

$3^{\circ }$ Alcohols: Do not undergo dehydrogenation. Instead, they typically undergo dehydration to form an alkene.

Final Answer: Option (A)
