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...

Of the 20 isomers for C4H5Cl, draw the isomers with a single ring and also containing one double bond. I have found 4 isomers that are correct but why are the structures on the left side incorrect? C4 Hg cl CH Сі CHE CHE . -** A A I LÀ CHE Correct Why are these hot isomers?
Draw the four geometric isomers of the alkene C3H4Br2. Be sure to draw out all bonds on the sp2 carbons.
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(s) of all of the alkene isomers, C6H12, that contain a methylene group. 2.Name all of the alkene isomers, C6H12, that contain an unbranched chain and that have E/Z isomers.
Draw the structure(s) of all of the alkene isomers, C H12, that contain an unbranched chain and that have EIZ isomers. • Consider E/Z stereochemistry of alkenes. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. • Separate structures with + signs from the drop-down menu. ChemDoodle
Draw three different alkene isomers of C5H7Cl. How mightyou use NMR to differentiate between them?
6. Draw and name all the alkene cis-trans isomers corresponding to the molecular formula C5H10. (Hint: there are only two.)
KMnO4 reacts with a non-aromatic alkene. Draw the reaction of cinnamaldehyde with KMnO4.
