Please give me the major organic products of the attached reactions. Stereochemistry is needed.
Please identify the structure giving the following spectra (NMW, IR, Mass Spec, etc.) (attached) and state how you arrived at your structure (give reasons such as peak identifcation and mass, etc.).
I attempted some of this but I am clueless as to some of the other stuff. Can you help? 2) Why are the products attached to C3 of 1,4 pentadiene more acidic than the methyl hydrogen atoms of propene? Maybe you can help me with this one. Are the C3 atoms more acidic because there is more s character involved with the ato
What is the absolute stereochemistry of the asymmetric carbon in compound O? When compound O is treated with lithium diisopropyl amide, followed by allyl bromide, compound P is produced as a single stereoisomer. What is the absolute stereochemistry of the newly produced asymmetric carbon in P? Provide concise explanations for
Draw the possible chair forms of cis and trans 1-isopropyl-3-methylcyclohexane. Are the two forms identical, enantiomeric, or diastereomeric? In each case, indicate which chair term will be more stable and explain why. Is either of these molecules chiral?
Draw the structure of the major organic product for each of the reactions shown below. If you can show stereochemistry, where relevant will help me out. Please see the attached file for full problem description.
I have tried to work out the following problem. Attached to this is a file that show NMR, IR and Mass spec info. I have come up with what I think the compound is but it does not work because the formula has more than one o. I have circled the carbonyl peak as well as the sp3 C-H peak.

I'm having some problems identifying the unknown compound based upon the information given. I provided as much information as I could with a possible compound, but I don't think it is correct. Can you please help me? Thanks!
Steam distillation may be used to separate a mixture of p-nitrophenol and o-nitrophenol. The ortho isomer distills at 93 degrees Celsius, the para isomer does not. Explain.
If 3-bromo-1-propanol is treated with NaOH, a compound of molecular formula C3H6O is formed. Suggest a structure for this product.
What orbitals are used to form the 10 covalent bonds in propane (CH3CH2CH3)? I think that the carbon-carbon bonds form because of sp3--sp3 overlap. The carbon-hydrogen bonds form because of sp3--s overlap. Is this correct??!!
What are the bond angles of the organic compound? Can geometry of geometries be named (tetrahedral, bent)? H H | | H - C - C - O - H | | H H
