Draw the conformation around relevant energy diagram and newman for the below isomer with rotation the C3-Cy bond.

Draw Newman projections for the anti, eclipsed, gauche and fully eclipsed conformations of Butane. Indicate their relative stabilities and the reasons for your ranking-need to discuss the stresses involved in each case.     Using suitable specific conformers of specific structures as examples, explain the difference between (a) angle strain  (b) torsional strain and (c) steric strain. Need to draw the confomers and structures         4)   Draw the most stable conformers using chair  structures of the following: (c) cis-1,2-Dibromocyclohexane     (d) trans-1,2-Dibromocyclohexane (e) cis-Decalin     (f) trans-Decalin .   Draw the most stable conformers of trans-1-Bromo-4-methylcyclohexane and cis-1-Bromo-4-methylcyclohexane. Which is more stable?  Explain the reason for your answer. Need to include a discussion of 1,3-Diaxial interaction

2. Consider the molecule 4-chloro-3-methylhex-2-ene a) Draw the constitutional structure for the molecule. b) Draw the staggered Newman projection looking along the C4-C5 bond c) Draw the structure for the (Z) geometric isomer of this molecule. Show how you worked that it is Z. d) Identify the chiral carbon atom, and draw the Renantiomer of this molecule. Show how worked out that it is R

I don't understand how to tell which one goes on which side. When I looked at the answer key to check my answer, I had H/Br and H/NH2 on the wrong sides

Write TRUE if the BOLD word/phrase makes the statement correct. Otherwise, write the correct WORD/PHRASE that will make the statement true. If there are two bold words/phrases in a number, write your answer for EACH of the bold words/phrases. 1.  The anti-staggered conformation of butane, in which the methyl groups have a dihedral angle of less than 180°, has the highest energy. 2.   The formation of 2-methylpropene as side product in the synthesis of tert-butyl chloride is a nucleophilic substitution reaction. 3.  The generation of tertiary carbocation is the rate-determining step in tert-butyl chloride synthesis.

6. What are conformers? Explain about conformers of butane in light of stability and energy. Also show the conversion of Sawhorse, Fisher and Newman projection of the molecule

Consider the molecule 1,2-dichloro-3-methyl-1-propanol and answer the following questions. Draw the Kekulé representation for this molecule clearly identifying the C1-C2 bond. Draw the Newman projection diagram for the least stable conformation of this molecule looking down the C1-C2 bond. Draw the sawhorse representation of the most stable conformation of this molecule looking down the C1-C2 bond.
