Interpretation: Synthesis of each of the following compound from (CH3)2CHCH2CH2Br is to be devised.
Concept introduction: Dehydrohalogenation is a chemical reactions which involves the removal of a hydrogen halide from an alkyl halide to furnish alkenes. The reacting alkyl halide must be able to form an alkene, which means they should have a replaceable hydrogen (Β-hydrogen). Some of the alkyl halides are unsuitable such as benzyl halides and aryl halides.
(c)
Interpretation: Synthesis of each of the following compound from (CH3)2CHCH2CH2Br is to be devised.

The reacting alkyl halide must be able to form an alkene, which means they should have a replaceable hydrogen (Β-hydrogen). Some of the alkyl halides are unsuitable such as benzyl halides and aryl halides. Halohydrin reaction is addition reaction of one Br and one OH to an alkene to form a hydroxyl derivative with alpha substituted halide.

(e)
Interpretation: Synthesis of each of the following compound from (CH3)2CHCH2CH2Br is to be devised.
Concept introduction: Epoxidation (or oxirane synthesis) is a chemical reaction in which an alkene in reacted with peroxide to give an epoxide. An epoxide is a cyclic ether with a three-atom ring having an equilateral triangle structure. Since, the three membered ring is highly strained (Baeyer strain), many

- Determine the pH of solution of HC3H5O2 By constructing an ICE table writing the equilibrium constant expression, and using this information to determine the pH. The Ka of HC3H5O2 is 1.3 x 10-5arrow_forwardDetermine if the following salt is neutral, acidic or basic. If acidic or basic, write the appropriate equilibrium equation for the acid or base that exists when the salt is dissolved in aqueous solution. If neutral, simply write only NR.

Next, record any regiochemistry or stereochemistry considerations relevant to the reaction. You should also record any key aspects of the mechanism, such as forma- tion of an important intermediate, as a helpful reminder. You may want to keep track of all reactions that make carbon-carbon bonds, because these help you build large molecules from smaller fragments.
