A. CH4+O2→ΔMo2O3\mathrm{CH}_{4}+\mathrm{O}_{2} \xrightarrow[\Delta]{\mathrm{Mo}_{2} \mathrm{O}_{3}}

B. 2CH3CH3+3O2→Δ(CH3COO)2Mn2 \mathrm{CH}_{3} \mathrm{CH}_{3}+3 \mathrm{O}_{2} \xrightarrow[\Delta]{\left(\mathrm{CH}_{3} \mathrm{COO}\right)_{2} \mathrm{Mn}}

C. (CH3)3CH→KMnO4\left(\mathrm{CH}_{3}\right)_{3} \mathrm{CH} \xrightarrow{\mathrm{KMnO}_{4}}

D. 2CH4+O2→Cu/523 K/100 atm.2 \mathrm{CH}_{4}+\mathrm{O}_{2} \xrightarrow{\mathrm{Cu} / 523 \mathrm{~K} / 100 \mathrm{~atm} .}

E. CH3−CH=CH−CH3→KMnO4/H+\mathrm{CH}_{3}-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}_{3} \xrightarrow{\mathrm{KMnO}_{4} / \mathrm{H}^{+}}
