For the hydrocarbons C_7 H_16, five of the constitutional isomers are shown. Draw all of the...
Laboratory Work 1. Draw the skeletal formulas and make models of the three constitutional isomers of C5H12. 2. Draw Kekule structures and make models of all the constitutional isomers of C2H4Cl2. 3. Draw Kekule formulas and make models of ethane, ethene, and ethyne. How does the geometry of their structures differ? Which compound contains sp hybridized carbons? 4. Draw and label the Newman projection and make the model of the anti-conformation of 1,2-dibromoethane. Rotate around the carbon-carbon bond...
2. Draw five different constitutional isomers with the formula C8H18. oceane NHq 3. List all the possible R S configurations of a molecule with 4 chiral carbon atoms.
3B) Draw the constitutional isomers of trimethylcyclopropane as
skeletal structures.
3C) For each constitutional isomer you drew in part (a), draw
any stereoisomers of that structure, explicitly showing
stereochemistry with dash/wedge bonds. Use skeletal structures.
2. This molecule has a ring strain of 70 kl/mol. Circle which type of strain is most important, and explain why you circledit: Angle torsional steric 3. Only one stereoisomer of this compound is stable - draw the relative stereochemistry at the ring Junction with...
1. Draw skeletal structures for all 10 constitutional isomers of C5H10F2 that have 4 carbons in the main chain and provide its IL;PAC names. Hint: Place the 2 atoms of fluorine on the first carbon for the first compound then just move one fluorine atom along the chain and keep one on the first carbon for the subsequent ones. Do the rest of the isomers in a systematic way too. The name of the substituents are: CIL methyl, F fluoro...
Week 10- Constitutional isomers Constitutional isomers have the same molecular formula, but their atoms are bonded in different orders. These may be further distinguished as chain isomers, which differ only in hydrocarbon chain structure, positional isomers, which differ in the location of a functional group, and functional group isomers which differ in the nature of their functional groups. Typically chain and position isomers show only modest differences in their physical and chemical properties, while functional group isomers differ greatly from...
6). There are five distinct constitutional isomers and stereoisomers for the formula CH.Cl2. A) (10 pts) Draw all five structures, using either wedge/hash (sawhorse) or Fischer Projections, B) (6 pts) Assign the R/S designations to all chiral centers. (Mark any achiral carbons with an "x"). C) (4 pts) Indicate which pair(s) of structures, if any, represent enantiomers.
Five of the constitutional Isomers of C_1 H_0 are cyclic compounds. Draw the one that has the lowest heat of combustion.
1. Draw the structure of n-pentane and all of its constitutional isomers. 2. Draw (showing stereochemistry) the meso isomer of 2,3-dibromobutane. 3. Draw two examples of cis-trans isomers with the molecular formula C6H12, one pair containing a double bond and pair containing a ring. (Four structures in total)
Draw all 5 of the constitutional and geometric isomers of C3H5Br and label which are cis and which are trans.

Then, draw and level properly all axial and equatorial positions on chair form of cyclohexane. 2) Draw chair, half-chair and boat conformations of ethyl cyclohexane and draw an energy diagram to explain their relative stability: 3) Draw two possible chair conformations for each of the mono-substituted cyclohexanes and determine their relative stability with proper explanation. OH 4) Draw two possible chair conformations for each of the di-substituted cyclohexanes and determine their...
