For the stereoisomers below, use the r/s configuration given in the compound name to finish drawing the structure by connecting the appropriate groups. be sure to specify the stereochemistry via wedge-and-dash bonds. if needed, you may restore a module to its orignal state by clicking on the module and then clicking on the red over-under arrows.

the right answer is c i just did the question.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
