Concept introduction:
The dehydration of alcohol leads to the formation of the alkene. This dehydration can be done by the acid-catalyzed mechanism. In this mechanism, the first step is the abstraction of a proton by the hydroxide group. The second step is the removal of water to give an intermediate “carbocation”. The third step is the generation of an alkene by the removal of

- 11. Specify the appropriate alkene for the synthesis of the given alcohol by hydroboration-oxidation?arrow_forwardAn unknown hydrocarbon A with the formula C6H12 reacts with 1 molar equivalent ofH2 over a palladium catalyst. Hydrocarbon A also reacts with OsO4 to give diol B. When oxidized with KMnO4 in acidic solution, A gives two fragments. One fragmentis propanoic acid, CH3CH2CO2H, and the other fragment is ketone C. What are thestructures of A, B, and C? Write all reactions and show your reasoning.arrow_forwardWhen bromine is added to two beakers, one containing phenyl isopropyl ether and the other containing cyclohexene, the bromine color in both beakers disappears. What observation could you make while performing this test that would allow you to distinguish the alkene from the aryl ether?arrow_forward
- 1. what are the differences between acyclic and cyclic forms in terms of their physical properties? 2. what is the role of vinegar in liquid-liquid extraction?arrow_forwardAn unknown hydrocarbon A with the formula C6H10 reacts with 1 molar equivalent of H2 over a palladium catalyst to give B C6H12 (Rxn 1). Hydrocarbon A also reacts with OsO4 to give the glycol C (Rxn 2). A gives 5-oxohexanal on ozonolysis (Rxn 3). Draw the structures of A, B, and C. Give the reactions.arrow_forwardAn organic compound A of unknown structure was found to have a molecular formula C8H16. When A was poured in water and heated, compound B having a molecular formula C8H18O was formed. B upon heating with sulfuric acid was converted to C as the major product which is identical to A. Ozonolysis of C gave one molecule each of two different products D and E, both having a molecular formula C4H8O. Write the reactions involved and determine the structure of A,B,C,D and E.arrow_forward

Nitrobenzene is added to the reaction mixture to serve as an oxidizing agent.The first step in the synthesis is the dehydration of glycerol to propenal. a. What product would be obtained if para-ethylaniline were used instead of aniline?b. What product would be obtained if 3-hexen-2-one were used instead of glycerol?c. What starting materials are needed for the synthesis of 2,7-diethyl-3-methylquinoline?arrow_forwardCompound A, C11H16O, was found to be an optically active alcohol. Despite its apparent unsaturation, no hydrogen was absorbed on catalytic reduction over a Pd/C catalyst. On treatment of A with dilute H2SO4, dehydration occurred and an optically inactive alkene B, C11H14 was produced as the major product. Alkene B, on ozonolysis, gave two products. Product C, C8H8O, was shown to be a methyl ketone while product D, C3H6O, was shown to be an aldehyde.arrow_forward
