Draw the structure of (2S,3Z)-2-fluoro-3-hexene. Use bold or
hashed wedges to indicate the configuration at stereogenic sp3 C
atoms. To indicate the stereochemistry about double bonds, place
the groups attached to the double bonds in appropriate positions
with 120 degree bond angles. Don't use bold, hashed, or criss-cross
bonds to indicate double-bond stereochemistry.
Please describe in detail the mechanism for the formation of
2R,3S/2S,3R-2,3-dibromo-3-phenylpropanoic acid. Based on the
stereochemistry of bromine addition.
Please, don't only use drawings (although they can be of help),
i would pefer it written. Thankyou.
Draw a planar structure for the following compound using dashed or solid wedges to show the stereochemistry of the substituent groups. To be graded properly, include the hydrogen atoms on the chirality centers (asymmetric carbons). Given cyclohexane in a chair conformation, substitute two of the H labels with methyl and tert-butyl to construct the more stable conformation of trans-1-tert-butyl-3-methylcyclohexane. Use the numbering provided on the ring.
Draw the condensed structural formula and zigzag structure of
the following isomers:
Cis-2,3 – dimethyl cyclohexane
1-brom- 3,3- dimethtylheptane
Isopropyl cyclobutane
3,3 – dimethyl- 2-propyl -cyclopentane
2-ethyl-3,3-dichlorohexane
Draw the Lewis structure for molecules
CH3OCH2CH3 and
CH3COCH3. Then...
a) indicate the location of the partial charges
b) Identify their molecular dipole moments.
Draw the structure of protonated histidine and indicate (draw
and name) all possible non bonding interactions with water. include
H bonding, and Hydration Spheres
For each of the following: draw the Lewis structure (use o whenever possible), name the molecular shape, and indicate if it is polar or nonpolar. a. SBr2 b. BrH3 c. SiF4 d. H2Oe. CH3F f. SiO2 g. SO2 h. NI3
