Which of the following is true regarding oxidation of an ethanol to an ethanal:
Correct answer: C. >CH2 is oxidized to -CHO group
- A. - CH3 is oxidized to CH2-OH
- B. - OH is oxidized to-CO group
- C. >CH2 is oxidized to -CHO group
- D. -CH2OH is oxidized to -CHO
Explanation
Explanation is given as: During the oxidation of ethanol to ethanal, the carbon atom (CH2) adjacent to the hydroxyl group (OH) in ethanol is oxidized to form the carbonyl group (-CHO) in ethanal. In the process, two hydrogen atoms are removed from the carbon (CH2) to form the carbonyl group (-CHO), and the alcohol functional group (-OH) is converted into an aldehyde functional group (-CHO). This reaction is commonly referred to as the oxidation of a primary alcohol to an aldehyde. Therefore, option C is correct.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
