3. Answer the following questions based on the reaction scheme below. a. Use wedged and dashed lines to draw the (2S,4R)-2-iodo-4-methoxypentane configuration of 2-iodo-4-methoxypentane in labeled box. b. Draw the product(s) of the nucleophilic addition reaction shown. Make sure to use wedged and dashed lines to clearly show the resulting stereochemistry at each chiral center. Label each chiral center as R or S. If there is more than one possible product, draw one in each box - if not, leave one box blank. c. Write the correct chemical name of each product(s) in the labeled boxes. 2-iodo-4- methoxypentane + NaOCH3 K[C6H1310] Product Name: Product Name: d. Are all the product(s) chiral? If your answer is 'yes' write 'yes' in the box below. If your answer is 'no', provide an explanation in 3 sentences or less in the box below.
Reactive Intermediates
In chemistry, reactive intermediates are termed as short-lived, highly reactive atoms with high energy. They rapidly transform into stable particles during a chemical reaction. In specific cases, by means of matrix isolation and at low-temperature reactive intermediates can be isolated.
Hydride Shift
A hydride shift is a rearrangement of a hydrogen atom in a carbocation that occurs to make the molecule more stable. In organic chemistry, rearrangement of the carbocation is very easily seen. This rearrangement can be because of the movement of a carbocation to attain stability in the compound. Such structural reorganization movement is called a shift within molecules. After the shifting of carbocation over the different carbon then they form structural isomers of the previous existing molecule.
Vinylic Carbocation
A carbocation where the positive charge is on the alkene carbon is known as the vinyl carbocation or vinyl cation. The empirical formula for vinyl cation is C2H3+. In the vinyl carbocation, the positive charge is on the carbon atom with the double bond therefore it is sp hybridized. It is known to be a part of various reactions, for example, electrophilic addition of alkynes and solvolysis as well. It plays the role of a reactive intermediate in these reactions.
Cycloheptatrienyl Cation
It is an aromatic carbocation having a general formula, [C7 H7]+. It is also known as the aromatic tropylium ion. Its name is derived from the molecule tropine, which is a seven membered carbon atom ring. Cycloheptatriene or tropylidene was first synthesized from tropine.
Stability of Vinyl Carbocation
Carbocations are positively charged carbon atoms. It is also known as a carbonium ion.
