Which of the Following Reactions is an Oxidation Reaction

Question

Which of the following reactions is an oxidation reaction? A) NaOH +HCl $\rightarrow$ NaCl + H2O B) CH3COOH $\rightarrow$ CH3COO^- +H⁺ C) CH3CHO $\rightarrow$ CH3CH2OH D) CH3CH2OH $\rightarrow$ CH3CHO +H2O E) CH2=CH2+ H2O $\rightarrow$ CH3CH2OH

Accepted Answer

In option D, an alcohol (CH3CH2OH) is being converted to an aldehyde (CH3CHO) and water (H2O), indicating the loss of hydrogen from the alcohol, which is a characteristic of oxidation reactions.
