Given below are two statements: Statement I: trans -But-2-ene upon treatment with Br ₂ in CCl ₄ gives the following product Statement II: cis -But-2-ene upon treatment with alkaline KMnO ₄ gives the following product In the light of the above statements, choose the most appropriate answer from the options given below.

Step-by-step solution

Reaction of trans-but-2-ene with Br₂ in CCl₄ proceeds via anti-addition to give meso-2,3-dibromobutane. In the Newman projection given in Statement I, the front carbon has Br at 0^ , Me at 120^ , and H at 240^ . The back carbon has Br at 180^ , Me at 60^ , and H at 300^ . For this staggered conformation to be meso, it must have a center of inversion, meaning a group at angle on the front carbon must have an identical group at + 180^ on the back carbon. While the Br atoms are opposite ( 0^ and 180^ ), the front Me a
