Question
The reactions which produce alcohol as the product are: A. CH _ 4 + O _ 2 [ ] Mo _ 2 O _ 3 B. 2 CH _ 3 CH _ 3 +3 O _ 2 [ ] ( CH _ 3 COO )_ 2 Mn C. ( CH _ 3 )_ 3 CH KMnO _ 4 D. 2 CH _ 4 + O _ 2 Cu / 523 ~K / 100 ~atm . E. CH _ 3 - CH = CH - CH _ 3 KMnO _ 4 / H ^ + Choose the correct answer from the options given below :
Options
- A. A, C and E Only
- B. A and D Only
- C. C and D Only
- D. B, D and E Only
Step-by-step solution
Analyzing each reaction for alcohol production: Reaction A: CH_4 + O_2 Mo_2O_3, produces formaldehyde, not alcohol. Reaction B: 2CH_3CH_3 + 3O_2 (CH_3COO)_2Mn, produces acetic acid, not alcohol. Reaction C: (CH_3)_3CH KMnO_4 tert-butyl compound undergoes oxidation to produce tert-butyl alcohol as the primary product. Reaction D: 2CH_4 + O_2 Cu/523K/100atm produces methanol (CH₃OH), a primary alcohol. Reaction E: The diene compound with KMnO_4/H^+ produces vicinal diol, which is technically an alcohol but not a simple monoalcohol. The reactions that predominantly produce alcohols as main products are C and D.
