Q. The reactions which produce alcohol as the product are :

A. CH₄ + O₂ Mo₂O₃, Δ →

B. 2CH₃CH₃ + 3O₂ (CH₃COO)₂Mn, Δ →

C. (CH₃)₃CH KMnO₄ →

D. 2CH₄ + O₂ Cu / 523 K / 100 atm →

E. CH₃ – CH = CH – CH₃ KMnO₄ / H⁺ →

Choose the correct answer from the options given below :

Correct Answer: C and D Only

Solution

Reaction C involves oxidation of isobutane with KMnO₄, which leads to formation of tert-butanol under controlled conditions.

Reaction D represents controlled oxidation of methane using Cu catalyst at high pressure and temperature, producing methanol.

Reaction A produces formaldehyde, not alcohol.

Reaction B results in formation of aldehydes and acids, not alcohols.

Reaction E with acidic KMnO₄ causes oxidative cleavage of alkene, forming ketones or acids instead of alcohols.

Hence, alcohols are produced only in reactions C and D.
