Stereochemistry Questions: Trivia Quiz!

Can you identify what stereochemistry is? Stereochemistry entails studying the relative spatial composition of atoms that create the formation of molecules and manipulation. The stereochemistry study concentrates on stereoisomers, which have the same molecular formula and cycle of bonded atoms but differ in their atoms' three-dimensional orientations in space. It can also be referred to as 3D chemistry. This quiz will show you that stereochemistry is an essential branch of chemistry.
