NPD1 is a potent natural anti-inflammatory agent.a.Label each carbon–carbon double bond as conjugated or isolated. b.Label each double bond as E or Z. c.For each conjugated system, label the given conformation as s-cis or s-trans.arrow_forwardDraw the planar (Haworth) structure for cis-1-ethyl-2- methylcyclohexane. (b) Draw the two ring - flipped chair conformations. (c) Circle the more stable chair conformation (circle both if they are equal in energy). Draw the Haworth structure and the two ring-flipped conformations of 1, 2, 4- trimethylcyclohexane (Compound D) on the frames below, b) Circle the more stable chair conformation (circle both if they are equal in energy). Haworth Structurearrow_forwardD-Pseudoephedrine, a decongestant that shrinks blood vessels in the nasal passages (treating stuffy nose), has the structure shown below. 1. What is the absolute configuration (R/S) of the carbon with – OH? 2. What is the absolute configuration (R/S) of the carbon with – CH3 3. Draw an enantiomer of this molecule: 4. Draw a distereomer of this moleculearrow_forward
- Ethylene oxide reacts readily with HO- because of the strain in the three-membered ring. Explain why cyclopropane, a compound with approximately the same amount of strain, does not react with HO-.arrow_forwardPlace the following compunds in order from lowest to highest boling points. Explain why you have ranked each compound C6H14 CH3OH H2O C3H8arrow_forwardWhat is each compound’s systematic name? 1. (CH3)3CCH2CH2CH2CH(CH3)2 2.

- Draw the three constitutional isomers having molecular formula C7H14 that contain a ve-membered ring and two methyl groups as substituents. For each constitutional isomer that can have cis and trans isomers, draw the two stereoisomers.arrow_forward1) Are the molecules A and B... conformational isomers? Diastereomers? Enantiomers? Position isomers? Non-related? 2) What about the molecules B and C? 3) What about the molecules C and D?arrow_forwardDraw the bond-line formula of 3,4-dimethylhexane. Is geometric isomerism observed in 3,4-dimethylhexane? What structural features must be present for stereoisomers to exist?
