Question

Consider the reaction of trans-$2$-butene with $B{r}_2$ in $C{H}_{2}C{l}_2$ . Which statement concerning this reaction is correct?

• A. The product is optically active because it possesses two chirality centers.
• B. The product is optically inactive because it is a racemic mixture of enantiomers.
• C. The product is optically inactive because it is meso.
• D. The product is optically inactive because it does not possess any chirality centers.

Answer 1

The correct option is C The product is optically inactive because it is meso.

A meso compound is a non optically active set of stereoisomer.

This means that despite containing two or more stereogenic centre it is optically inactive.

Answer is $\left(C\right)$.
