What is the line structure, complete structural formula, and condensed structural formula for the following: Cyclopentane, 2- butene, 2-methylpropene, and 1-pentene
Decide which one of the following cycloalkanes shows cis-trans isomerism and draw a structural formula for its cis isomer. 1,2-dimethylcyclohexane ethylcyclopropane Decide which one of the following cycloalkanes shows cis-trans isomerism and draw a structural formula for its trans isomer. 1,1-dimethylcyclohexane 1,4-dimethylcyclohexane
Using the templates provided, draw the planar representation (use wedges and dashes!) and both chair conformations of the models of 1,2-dichlorocyclohexane in the table below Is one chair conformer lower in energy? If so, circle the appropriate conformer(s) above. Are the two chlorine atoms cis- or trans- to each other? Can both chlorine atoms be axial in any chair conformation? 72

Draw the structural formula of 3-ally-4-vinlcyclohexanone State University, Moorhead Draw the structural formula of 3-allyl-4-vinylcyclohexanone. The cyclohexanone ring template has been drawn for you, and the carbonyl carbon is carbon #1. (While both of the substituted carbons could have chirality, do not use hashes and wedges definition, because the stereochemistry at those centers is undefined.) Note: The carbonyl carbon will be #1. So your job is to figure out what vinyl and allyl substituents are. O
