Which of the following statements about alcohol oxidation is incorrect?
Correct answer: C. 3° alcohol is easily oxidized in the presence of K₂Cr₂O₇/H₂SO₄
- A. 1° alcohol oxidizes to form an aldehyde, which can be further oxidized to a carboxylic acid
- B. 2° alcohol oxidizes to form a ketone
- C. 3° alcohol is easily oxidized in the presence of K₂Cr₂O₇/H₂SO₄
- D. All are correct statements
Explanation
This statement is incorrect because tertiary (3°) alcohols are resistant to oxidation. They lack a hydrogen atom on the carbon that is bonded to the -OH group, which is necessary for this type of oxidation to occur easily.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
