Question

The number of stereoisomers obtained by bromination of trans-2-butene is (A) 1 (B) 2 (C) 3 (D) 4

Tardigrade Admin · Accepted Answer

As addition of Br2 is anti and trans-2-butene is used so meso form of 2,3-di-bromo-butane is formed which has 2 chiral carbon atoms. <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-4s1a3w8b65ie.png" />
