Sửa: \(KCHO\rightarrow RCHO\)
Sơ đồ phản ứng: \(R\overset{-1}{C}H_2OH+K\overset{+7}{Mn}O_4\rightarrow R\overset{1}{C}HO+\overset{+4}{Mn}O_2\downarrow+KOH+H_2O\)
\(\overset{-1}{C}\rightarrow\overset{+1}{C}+2e\) | \(\times3\) |
\(\overset{+7}{Mn}+3e\rightarrow\overset{+4}{Mn}\) | \(\times2\) |
PTHH: \(3RCH_2OH+2KMnO_4\rightarrow3RCHO+2MnO_2\downarrow+2KOH+2H_2O\)
