Given below are two statements: Statement I : trans-But-2-ene upon treatment with \( \text{Br}_2 \) in \( \text{CCl}_4 \) gives the following product (shown via Newman projection). Statement II : cis-But-2-ene upon treatment with alkaline \( \text{KMnO}_4 \) gives the following product (shown via Newman projection). In the light of the above statements, choose the most appropriate answer from the options given below:

  1. Both Statement I and Statement II are correct
  2. Both Statement I and Statement II are incorrect
  3. Statement I is correct but Statement II is incorrect
  4. Statement I is incorrect but Statement II is correct

Correct answer · Option 1

Both Statement I and Statement II are correct

Explanation

Addition of Br2 to trans-but-2-ene gives meso-2,3-dibromobutane (anti addition), and cis-but-2-ene with alkaline KMnO4 gives meso-butane-2,3-diol (syn hydroxylation). Both statements and projections are correct.
