Step-by-step solution
Let us determine the absolute configuration of the reactant. The priorities of the groups attached to the chiral center are: -Br (1) > -Et (2) > -Me (3) > -H (4). In the given 3D representation, the lowest priority group ( -H ) is on a dashed bond, meaning it is pointing away from the viewer. Looking at the remaining groups: -Br is pointing down-right, -Et is pointing down-left (on a wedge), and -Me is pointing straight up. The sequence from priority 1 2 3 is -Br -Et -Me , which traces a clockwise direction. Since
