- (a) Draw the molecular orbital picture for propa-1,2-diene, H2C=C=CH2. Hint: The three-dimensional geometry is shownin the chapter. (b) Draw the MO energy diagram for propa-1,2-diene. What is the HOMO? What is the LUMO?Please refer to the Newman projections shown below to when answering questions (a) – (f)Please help wiith the fourth one (C3H8O)
- 1. Draw structures of the most stable Newman projection for the image below2. Draw the five constitutional isomers having the molecular formula C4H6select the most stable isobutyl chloride newman projectionConsider 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.
- 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 Newman projection below. a. Draw a full Lewis structure of this molecule with R1=Me,R2=Et , and R3=iPr . b. Given the sizes of these R groups (R3R2R1) , does the Newman projection above show thelowest potential energy conformation of this bond? If not, draw a Newman projectionshowing the lowest P.E. conformation (sighting down this same bond). c. To draw a Newman projection in the lowest P.E. conformation, the following rule of thumbusually applies: Place the largest group on the front carbon anti to the largest group on theback carbon. Is your answer to the previous question consistent with this rule of thumb?I believe the first anwer is d and the second is a mixture of enantiomers
