The addition of $\mathrm{Br}_{2}$ to (E)-but-2-ene gives
1 (R, R)-2-3-dibromobutane
2 (R, S)-2-3-dibromobutane
3 (R, S)-2-3-dibromobutane
4 A mixture of $(\mathrm{R}, \mathrm{R})$ and $(\mathrm{S}, \mathrm{S})$ 2, 3 dibromobutane
Explanation:
The addition of bromine to E-but-2-ene provides (R, S) - 2 - 3 dibromobutane. Therefore, it is always anti as bromine atoms which is added on the opposite sides. The above reaction involve anti addition of bromine The name of obtained compound $(\mathrm{R}, \mathrm{S}), 2,3$ dibromobutane.
