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, CH12. Draw the condensed formula b) Build a model of methylcyclohexane (C;H2a) by replacing one of the hydrogens of cyclohexane with a methyl group. Draw the skeletal formula for methylcyclohexane. c) How many different isomers exist for methylcyclohexane (C-Ha)? d) Start...

TU c) Start with the model of propene built in 3a), substituting different hydrogen atoms of propene with a methyl group to form isomers of butene, CaHg. How many different isomers exist for butene (C4Hg)? Prepare models and draw the Lewis structures for each of the isomers. d) Two of isomers of butene comprise a pair of stereoisomers. Draw the skeletal structures and include IUPAC names for the cis and trans isomers. Recall in the cis isomer both methyl groups...

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...

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...
