A student oxidises butan-1-ol (CH3CH2CH2CH2OH\text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{OH}CH3CH2CH2CH2OH) to butanoic acid (CH3CH2CH2COOH\text{CH}_3\text{CH}_2\text{CH}_2\text{COOH}CH3CH2CH2COOH) using acidified potassium dichromate(VI).
What type of reaction occurs, and how does the number of hydrogen and oxygen atoms in each organic molecule change?
Reduction; the organic molecule gains two hydrogen atoms and loses one oxygen atom.
Oxidation; the organic molecule loses one hydrogen atom and gains two oxygen atoms.
Oxidation; the organic molecule loses two hydrogen atoms and gains one oxygen atom.
Dehydration; the organic molecule loses two hydrogen atoms and one oxygen atom.
