Question

When acetaldehyde is oxidized with acidified potassium dichromate, it forms ________.

Answer 1

• Acetaldehyde (${\mathrm{CH}}_3\mathrm{CHO}$) is an organic compound in which the functional group is an aldehyde group ($-\mathrm{CHO}$).
• Acidified Potassium dichromate (${\mathrm{K}}_2{\mathrm{Cr}}_2{\mathrm{O}}_7$) is a strong oxidizing agent due to which the aldehyde group will convert into a carboxylic acid group ($-\mathrm{COOH}$).
• The reaction is given below:

$\underset{\mathrm{Acetaldehyde}}{{\mathrm{CH}}_3\mathrm{CHO}\left(\mathrm{l}\right)}\stackrel{{\mathrm{K}}_2{\mathrm{Cr}}_2{\mathrm{O}}_7}{\to }\underset{\mathrm{Acetic}\mathrm{acid}}{{\mathrm{CH}}_3\mathrm{COOH}\left(\mathrm{l}\right)}$

• So, when Acetaldehyde is oxidized with Acidified Potassium dichromate, it forms Acetic acid (${\mathrm{CH}}_3\mathrm{COOH}$)
