- 1. how many stereoisomers are possible for 9,10- dibromo hexadecanoic acid? 2. Addition of bromine to palmitoleic acid primarily yields a set of enantiomers, (±) -three-9,10-dibromo hexadecanoic acid. The addition of bromine is an anti-addition to the double bond (ie, it appears to occur through the intermediary of the bromonium ion). Taking into account the stereochemistry of the cis double bond of palmitoleic acid and the stereochemistry of adding bromine, Write a three-dimensional structure for (±) -three-9,10-dibromo hexadecanoic acid!arrow_forwardA) Considering compounds 2a through 2l, identify: 1)one pair of geometric isomers 2)two pairs of enantiomers and 3)three pairs of identical molecules B) Give the names, including the configurations, of each of the geometric isomers and of each of the enantiomers identified in 1A and 1B. Draw the relevant structures. C) Sort compounds 2a, 2b, 2c, 2f and 2k in order of increasing solubility in water and briefly justify.arrow_forwardAccording to the Woodward-Hoffmann rules, is this cycloreversion reaction possible under these conditions?arrow_forward
- Doxaprost, an orally active bronchodilator patterned after the natural prostaglandins , is synthesized in the following series of reactions starting with ethyl 2-oxocyclopentanecarboxylate. Except for the Nef reaction in Step 8, we have seen examples of all other types of reactions involved in this synthesis. Q. Assuming that the two side chains on the cyclopentanone ring are trans, how many stereoisomers are possible from this synthetic sequence?arrow_forward(a) How many Stereoisomers are possible for 9,10- dibromoexadecanoic acid?(b) Addition of bromine to palmitoleic acid primarily yields a set of enantiomers, (±) -three-9,10-dibromohexadecanoic acid.

- An oxygen containing compound shows strong Infrared radiation absorption at 1630 - 1780 cm^-1 and 3200 - 3550 cm^-1. What type of compound is it likely to be? A. An ether B. A ketone C. A carboxylic acid D. An alcohol E. An aldehydearrow_forwardProvide a mechanism which explains the following conversions. Include all intermediates (where appropriate) and watch your arrows and chargesarrow_forwardOn being heated with a solution of sodium ethoxide in ethanol, compound A (C7H15Br) produced a mixture of two alkenes B and C, each of which had the molecular formula C7H14. Catalytic hydrogenation of major isomer B or minor isomer C gave only 3-ethylpentane. Suggest structures and mechanisms for compounds A, B, and C consistent with these observations.arrow_forward
