The given
Concept Introduction:
Carbocation: it is carbon ion that bears a positive charge on it.
Leaving group: it is a fragment that leaves from a substrate with a pair of electrons via heterolytic bond cleavage.
Carbocation stability order:
Resonance stabilization: Due to the delocalization of electrons within the molecule the overall energy becomes lower and makes that molecule more stable.
Nucleophile: Nucleophiles are species that donate an electron pair and are also termed as electron-hating species.
Electrophile: Electrophiles are species that accept an electron pair and are also termed as electron-loving species.
(b)
Interpretation:
The given alkenes should be arranged in increasing rate when they react with

- Ethers can be prepared by reaction of an alkoxide or phenoxide ion with a primary alkyl halide. Draw the structure of the expected organic product of the reaction of iodomethane with the following alkoxide ion: CH3 H3C O Na You do not have to consider stereochemistry. You do not have to explicitly draw H atoms. • Do not include lone pairs in your answer. They will not be considered in the grading. • Do not include counter-ions, e.g., Na", I, in your answer. орy вste ChemDoodlearrow_forwardExplain the different products of the following two reactions by considering the mechanism by which each reaction proceeds.

- 1) 3- Methyl-2-butanol will react with H2SO4 to give two isomeric alkenes. Write suitable reaction mechanism to show how these isomeric products are achieved and indicate the major product. Write the IUPAC name for each product.arrow_forwardDescribe how 1-ethylcyclohexanol can be prepared from cyclohexane. You can use any inorganic reagents, any solvents, and any organic reagents as long as they contain no more than two carbons.arrow_forwardWhen cyclohexene is reacted with hydrobromic acid in acetic acid, the major product is bromocyclohexane. There is a small amount of cyclohexyl acetate formed. What is the mechanism that forms both compounds? What is the purification procedure that isolates both compounds?arrow_forward
- One compound that contributes to the “seashore smell” at beaches in Hawai‘i is dictyopterene D', a component of a brown edible seaweed called limu lipoa. Hydrogenation of dictyopterene D' with excess H2 in the presence of a Pd catalyst forms butylcycloheptane. Ozonolysis with O3 followed by (CH3)2S forms CH2(CHO)2, HCOCH2CH(CHO)2, and CH3CH2CHO. What are possible structures of dictyopterene D'?arrow_forwardUsing your reaction roadmap as a guide, show how to convert cyclohexane into hexanedial.
