Answer:
This bond rotation generates a new isomer
Explanation:
This process described in the question is called stereoisomerism. This is a process in which molecules have the same molecular formula and bonding but differ in there three-dimensional structure in space. These three-dimensional spacial orientation can be changed by turning a bond around a fixed point making the functional change position in space. This rotation does not bring about a new molecule but a new isomer through a process known as stereoisomerism.
