WebTranscript. Isomers are compounds of the same molecular formula but different molecular structures. There are four important types of isomers. Structural isomers atoms are bound in different orders while stereoisomers are bound in the same order but oriented differently. Geometric isomers involve different arrangement about a double bond. WebOptical isomerism occurs in compounds which have four different groups attached to a single carbon atom. In this case, the product molecule contains a CH 3, a CN, an H and an OH all attached to the central carbon atom. The reason for the formation of equal amounts of two isomers lies in the way the ethanal gets attacked. chime chromeWebJan 23, 2024 · In contrast to more well-known constitutional isomerism, which develops isotopic compounds simply by different atomic connectivity, stereoisomerism generally maintains equal atomic connections and … grading tonsil size
