Stereochemistry, Bonding and Formation

Which chair term will be more stable and explain why?

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?

Determining a structure

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.

Structures and fragmentation patterns in mass spectra

Suggest structure fragmentation patterns that account for the following observed peaks in the mass spectra. A) 5-methyl-2-hexanone, m/e= 71, 58, 43 B) C6H5CH2OCH3, m/e= 122, 121, 91, 77 C) 1-bromopropane, m/e= 124,122, 43, 29, 15

Conformation structures

A) Draw the most stable chair conformation of cis-1-cyclopropyl-2-methlcyclohexane. B) Draw the most stable conformation of trans-1-isobutyl-4-methylcyclohexane in both the chair conformation and the wedge structure.

Deriving Unknown Chemical Compound

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! An unknown compound containing C, H, and one kind of heteroatom only shows a molecular ion peak

Steam Distillation

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.

Aromatic Rings

In the formation of diacetylferrocene, the product is always the one in which each ring is monoacetylated. Why is no diacetylferrocene produced in which both acetyl groups are on the same aromatic ring?

Types of orbitals use in the molecule: CH3CH2CH3

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??!!

Write structures that all have the molecular formula C4H8O2

Please write structures for at least 15 different compounds that all have the molecular formula C4H8O2. For one structure, provide examples of that structure using the dash format, the condensed format, the bond-line format, and the full three-dimensional format. Use the dash format to describe the remaining structures. Id

Molecular Structures for C17 H27 NO2.

I need the molecular structure for effexor xr. Please label all cabons, hydrogens, nitrogen,and oxygens. The formula is C17 H27 NO2. I don't understand the structure or meaning of the ring inside of the hexagon, does it stand for benzene or something ike that and what is the actual structure of it.
