Answer
This is a meso compound.
Work Step by Step
First method:
Try to find a symmetry plane.
- As we can see in the image, if we put a imaginary vertical or an horizontal line on the center of the compound, both sides will be exactly the same.
Second method:
Draw the enantiomer, and compare it with the original one.
- If we put an imaginary mirror on the side of the compound, we will see exactly the same compound, with the same groups in the same positions.
** If we put the mirror on the back, we will get the same enantiomer, but it will be flipped, so you just need to imagine it rotating 180 degrees (horizontally).
