हिन्दीGiven 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:
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.
