Q35.The stereoisomers that are formed by electrophilic addition of bromine to trans - but - 2 - ene is/are : (1) 2 identical mesomers (2) 2 enantiomers (3) 2 enantiomers and 2 mesomers (4) 1 racemic and 2 enantiomers
What This Question Tests
This question assesses the understanding of stereochemical outcomes in electrophilic addition reactions, specifically that anti-addition to a trans-alkene like trans-but-2-ene yields a meso compound.
