Help Organic Chem part 7 Do the two examples by drawing the perspective drawings in the box. And include the angle. Perspective drawings (Haworth projections) Cyclic structures can be described using bond-line drawings, but can also be drawn using perspective drawings (Haworth Projections), which are used very often in biochemistry. In perspective drawings, the ring is viewed from a "side perspective" and the substituents are drawn pointing either straight up or straight down. cyclobutane (C4H3) cyclohexane (C6H12) Wedge-Dash drawing Perspective...
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...
3. Cyclic compounds The presence of the ring in all but very large ring cyclic molecules prevents full rotation of the ring atoms. For this reason, stereoisomerism may also occur in cyclic molecules. a) Prepare a model of cyclohexane, C6H12. Draw the condensed formula. b) Build a model of methylcyclohexane (C7H14) by replacing one of the hydrogens of cyclohexane with a methyl group. Draw the skeletal formula for methylcyclohexane. 2 c) How many different isomers exist for methylcyclohexane (CyH34)? d)...
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...
A. Enantiomers: Certain substances have the unique property of rotating the plane of plane-polarized light. Such light rotation is detectable with the aid of a polarimeter. In order for a molecule to be optically active it must be chiral. Chiral objects lack a plane of symmetry and are non-superimposable on their mirror images. A sp?- hybridized carbon atom can fulfill these requirements if all four of its substituents are different. 1. Methane a) Prepare a methane molecule and then substitute...
