Which of the following alcohols needs acidic KMnO ₄ to convert it into aldehyde or ketone?

Options

  1. AEthanol
  2. Bpropan-1-ol
  3. Cpropan-2-ol
  4. D2 -Methy 1 propan -2 -ol

Correct answer

D. 2 -Methy 1 propan -2 -ol

Step-by-step solution

2-methyl propan-2-ol To convert 2-methyl propan-2-ol to ketone, acidic KMnO ₄ is required. Under strong reaction conditions such as powerful oxidising agents ( KMnO ₄ ) and extreme temperature, cleavage of various C - C bonds occurs.
