For octa-1,2,5,7-tetraene please explain in detail why the number of stereoisomers is 3 because of cis/trans or E/Z. I know how to do molecules with chiral C's, but I do not know how to do long chain alkenes.
For octa-1,2,5,7-tetraene please explain in detail why the number of stereoisomers is 3 because of cis/trans...
Please explain in detail why alkenes and water do or do not mix.
I don't know if this is correct and I need some
guidance.
OH trans Cis 3. When an unknown stereoisomer of but-2-ene reacts with KMnO, in aqueous KOH, a racemic diol is formed. Was the original alkene the cis or the trans isomer? Explain your reasoning. OH . Kinay L KMnO4 l а акон OH 04 on The original alkene, was trans because the cis alkene. has the OH groups added to the same side and creates amese compound. For...
Please explain why is it Cis or trans. How can we differentiate
the isomers? Why one shift futhur downfield than the other?
Problem 6 (1 pt Use the IHNMR and 13C NMR spectra to determine the structure of a compound whose chemical formula is C2H2C12 and assign the peaks in each spectrum. Note: In both iHNMR and 13 spectra, ignore the TMS peak at 0 ppm. IH NMR: doublet at 5.74 ppm (1) and a doublet at 4.44 ppm (l)....
i
know with E pentene it would be trans and Z pentene it would be
cis. but im confused at to what that has to do with heat of
hydrogenation
16. Which has the smaller heat of hydrogenation, (E)-2-pentene or (Z)-2-pentene? What is the structural origin of this difference? Please give your answer here:
Please rank the stability of 1-butene, trans-2-butene, and cis-2-butene, and explain the reasoning behind the heats of hydrogenation, as it relates to each molecule. In your own words, explain the difference between 1,2 and 1,4 additions. Please include terms of allylic carbocation, delocalization, and resonance. 3-5 sentences will be sufficient. Please explain, detail, the differences in the hydrohalogenation across the double bond with regards to Markovnikov and Non-Markovnikov this is all one question please type answer i cannot always understand...
1. Describe properties about alkenes and alkynes. 2. The two stereoisomers of l-bromo-1,2-dichloroethene cannot be designated as cis and trans in the normal way because the double bond is trisubstituted. They can, however, he given (E) and (Z) designations. Write a structural formula for each isomer and give each the proper designation 3. Studies of numerous alkenes reveal a pattern of stabilities that is related to the number of alkyl groups attached to the carbon atoms of the double bond....
Chapter 11: 1. What is a prime rule in naming alkenes? a. Find the longest carbon chain. b.Find the longest carbon chain containing the alkene. c. Find whether the alkene has a cis- or trans- configuration. d.Find how far the alkene functionality is from either end. 2. What is the IUPAC name of the following alkene? a. cis-5-methyl-2-heptene b. trans-2-ethyl-4-hexene c. trans-5-methyl-2-heptene d. trans-3-methyl-5-heptene 3. What is the hybridization, geometry, and bond angle of the carbon marked by an asterisk?...
please in as MUCH detail explain why this is the answer. what
are pre and post trans/transl. and ALSO please explain what A
through D are (definition and what it refers to in genetics)
37. Genetic regulation in eukaryotes can take place at a variety of levels from pre- transcriptional to posttranslational. At what level is genetic regulation considered most likely in prokaryotes? A) polyadenylation of the 3' end of the mRNAs B) capping ranscriptional D) intron processing E) exon...
Explain why 3-methylcyclohexene is more stable than
methylcyclohexane.

Assignment 3: Chiral Carbons and Stereoisomers On a page titled Chiral Carbons draw using a chemical drawing program or other computer generated form the expanded structure of your molecule. No hand drawn structures will be accepted. O Determine if your molecule contains any chiral carbons. If there are chiral carbons in your molecule, circle or highlight all of them. If your molecule does not contain any chiral carbons explain why none of the carbons are chiral. One a...
