- Draw and name the seven aldehydes and ketones with the formula C5H10O. Which are chiral?arrow_forwardA difficult problem in the synthesis of PGF2α is the introduction of the OH group at C15 in the desired configuration. a. Label this stereogenic center as R or S. b. A well-known synthesis of PGF2α involves reaction of A with Zn(BH4)2, a metal hydride reagent similar in reactivity to NaBH4, to form two isomeric products, B and C.

- 2-bromopentane, when treated with alcoholic KOH yields a mixture of three alkenes A, B and C. Identify A, B and C. Which is predominant?arrow_forwardWrite the structure of the compound E,E-2,4-Hexadien-1-ol and label each non-equivalent carbon with a letter, A,B,C..arrow_forwardPropose the structure of the following: a. An alkane, C6H14 b. A crylic saturated hydrocarbon, C6H12 c. A diene (dialkene), C5H8 d. A keto alkene, C5H8Oarrow_forward
- Unknown Q is determined to have a molecular formula of C6H12O. Q is not optically active, and passing it through achiral column does not separate it into enantiomers. Q does not react with Br2, nor with cold, dilute KMnO4, nor doesit take up H2 under catalytic hydrogenation. Heating of Q with H2SO4 gives product R, of formula C6H10, which canbe separated into enantiomers. Ozonolysis of a single enantiomer of R produces S, an acyclic, optically active ketoaldehyde of formula C6H10O2. Propose structures for compounds Q, R, and S, and show how your structures would reactappropriately to give these results.arrow_forwardName the structure and give it's stereogenic centers as well as it's stereochemistry (R or S)arrow_forwardWhich of the structures below is (4R)-4ethyl-2,4- dimethylcyclohexan-1-one?arrow_forward
