Concept explainers
(a)
Interpretation: A name for given compound needs to be assigned.
Concept Introduction: Nomenclature of
First method- Parent
Second method: Oxirane ring is considered as parent and groups attached to it are considered as substituents.
(b)
Interpretation: A name for given compound needs to be assigned.
Concept Introduction: Nomenclature of epoxides: Epoxides are cyclic ethers having an oxygen atom incorporated in three-membered ring system having up to four R groups. Due to ring strain, they are more reactive than other ethers. The simplest epoxide does not have any R group and known as ethylene oxide. Naming is done by two methods.
First method- Parent alkane chain is identified and oxygen is considered as substituent on that chain. Location of epoxide group is written with two numbers with suffix epoxy. While naming, epoxy substituents are alphabetically arranged.
Second method: Oxirane ring is considered as parent and groups attached to it are considered as substituents.

- A student proposes the transformation below in one step of an organic synthesis. There may be one or more reactants missing from the left-hand side, but there are no products missing from the right-hand side. There may also be catalysts, small inorganic reagents, and other important reaction conditions missing from the arrow. • Is the student's transformation possible? If not, check the box under the drawing area. . If the student's transformation is possible, then complete the reaction by adding any missing reactants to the left-hand side, and adding required catalysts, inorganic reagents, or other important reaction conditions above and below the arrow. • You do not need to balance the reaction, but be sure every important organic reactant or product is shown. + T X O O лет-ле HO OH HO OH This transformation can't be done in one step.arrow_forwardDetermine the structures of the missing organic molecules in the following reaction: X+H₂O H* H+ Y OH OH Note: Molecules that share the same letter have the exact same structure.
