Imagine that this worksheet has sucked you the plane of the page, and you are now facing the indicated bond of the drawn molecule. a. Draw the six main Newman projections for the indicated bond: three eclipsed, three staggered. b. Label which conformers are eclipsed ands taggered.c. Identify the most and least stable conformer, and explain your reasoning.
Using your model, construct an energy diagram to show the variation in the free energy of the molecule as the FRONT ATOM is rotated CLOCKWISE from 0º to 360º in 60º increments. In your energy diagram, you should clearly show the relative energies of each conformer.
Square planar molecules with formula AB2C2 and octahedral molecules with formulas AB4C2 and AB3C3 feature diastereoisomers. Recall that trigonal bipyramidal geometry features two distinct positions: axial and equatorial. Draw all diastereoisomers for trigonal bipyramidal molecules with formula (a) AB4C and (b) AB3C2. You must indicate the stereochemistry using full and dashed wedges and label all positions as either axial (ax) and equatorial (eq)..
Please do parts A and B Consider (2R,3R)-2,3-diidobutane: (a) Draw a Fischer Projection of this structure with C1 on top and C4 on bottom. (b) Draw a Newman Projection of of the meso compound of 2,3-dibromobutane looking down the C2-C3 bond with C2 in front, and label your asymmetric carbons as S or R.
Stereoisomers share the same connectivity and differ only in the way their atoms are arranged in space. Draw the structure of a compound that is a stereoisomer of cis-1,2-dimethylcyclobutane.(Note that the question asks for a different stereoisomer of the named compound and not the named compound itself.)Use the wedge/hash bond tools to indicate stereochemistry where it exists.In cases where there is more than one answer, just draw one.
1.1 Build a model for line structure and use the template given to draw a Newman projection for this conformation of the compound when viewed along the C2-C3 bond. (template given in second photo) 1.2 why is this the most stable structure?

2.(a) Different conformations are found in 2-methylpentane. (i) Using Newman Projection, draw all the possible staggered and eclipsed conformations of pentane by referring to the bond rotation at C3-C4.(ii) Compare their stability and explain your answer.
Indicate the relationship between each pair. Choose from: configurational stereoisomers,conformers, constitutional isomers, or different formulas (Each term is used at least twice.)
Consider the molecule 1-bromo-2-methylbutane. C3 and C4 should be drawn as Et as in theexample. This group is called an ethyl group and can be considered a sphere about twice the sizeof a methyl group. Draw the following Newman projections sighting down the C1C2 bond... a. The lowest potential energy conformation. b. The highest potential energy staggered conformation.
Question: which of the following molecules will have the greatest difference in energy between its chair conformations? I understand that both B and D have chair conformations that are more favored one way than another (B because it's cis 1-3 where both substituents are equatorial or axial and D because for monosubstituents there are 1-3 diaxial interaction if the substituent is axial position) but why is B greater than D? Is it due to the fact it is two substituents over one? Can you explain this for me?
