7. D-glucose, blood sugar, exists in two forms; ring open and ring closed. Don’t worry about the chemistry of ring closure (but FYI, arrows are pointing at the atoms involved in this cyclization). This is an example of a problem that has all kinds of irrelevant information that you have to ignore as you search for the actual question. Consider the ring open form of D-Glucose What is the absolute configuration at C-3?How many stereoisomers does the ring open form of D-glucose have? Using Fischer projections, draw its enantiomer and one diastereomerlow many stereoisomers does the ring closed form shown below have? na open form

Stereoisomers print/draw the expanded structure of 4-bromo-4-ethylhept-1-ene. Calculate the maximum number of possible stereoisomers of the molecule using the following formula. Maximum number of possible stereoisomers = 2n (where n= the number of chiral carbons in your molecule). This calculation does not include E- or Z- isomers for any compounds containing double bonds. Draw the possible stereoisomers of the molecule. Note that E-, Z- isomers of each stereoisomer are also possible and would not be accounted for by the formula above; draw any E- or Z- isomers.

What is your understanding of the term organic now ? Describe the connection you see between the various definitions?

Rodriogo is trying to complete a crossword puzzle, but he's stuck on a seven letter word that begings with "org". Which of his friends will most likely be the fastest to figure out what the word is organic?  A. Jay, who just finished watching a documentary about crossword puzzles  B. Li, who prefers to buy organic produce when its on sale  C. Tonya, whos taking organic chemistry this semester  D. Trevor, who just woke up from a dream about being chased by gaint ears of corn

caq2 Please help with Organic Chemistry question. Thanks

Please answer 4,8

Name the family to which each organic compound belongs. The first answer has been filled in for you. compound CH₂ || CH₂-C-0-C- CH₂ O || CH₂ || CH–C—NH, CH, OH I | CH₂-CH-C || || CH,—C–NH CH, X family ester 0

Write the organic products for the following reactions

1.Draw a structure that corresponds to the incorrectly named: 6-tert-butyl-3-isopropylhexane. 1b. Rename the compound above according to the IUPAC rules. 1c. Draw a circle around every methine (3o) carbon and a square around every 4o carbon. How many 1o and 2o carbons arepresent?

Replace one H on propane with Br. Does it matter which H is replaced? Yes or No (circle) Are isomers possible for C3H¬B1? Yes or No (circle) Draw the expanded structures for all isomers and name each compound. As in question 1 on the previous page, use a number in front of the name to indicate the position for the bromine atom on the carbon chain. Consult with your instructor to make sure you've correctly drawn and named the structure(s) here. 3. Complete the following for compounds derived from butane, C4H10. Butane, C4H10 Lewis Structures & Name Are isomers possible? Yes or No (circle) Build a model & draw the line structures for all potential structural isomers of C4H10. Using your molecular models for the butane isomers as a guide, draw line structures for all monoiodo-derivatives of each of your isomers of butane having the molecular formula C4H9I. Give the IUPAC name for each compound.
