18. Complete each of the following reactions. Then determine where the equilibrium is moving it is say which one favors the formation of the reactants and which one favors the formation of the products. If you cannot decide with the structure, compare the pka value of the acid with that of the conjugate acid. 4. CHỊCH NH • Hỏi - CHCH-CC-H.H c. CHOH + H-Br =...

(a) (b) .CI For each compound below 1. Draw representations for the cis and trans isomers using a hexagon for the six- (i) membered ring, and wedges and dashes for substituents. Draw the two possible chair conformations for the cis isomer. Which conformation, if (ii) either, is more stable? Draw the two possible chair conformations for the trans isomer. Which conformation.

Procedure B. 1. Build two models of 1, 2-dimethyleyclopentane. The two methy can be on the same face or opposite faces of the ring. No matter how t molecule is twisted, they cannot be superimposed on each other. These compounds are stereoisomers of each other. 2. When two groups are present, the prefix cis (same face) or trans (opposite face) can be used in IUPAC nomenclature to specify which stereoisomer is being considered. For drawings, a solid wedged line in...

6. Build the cyclobutane ring and study the angle strain and torsional strain. Draw the structures to explain these factors. 7. The conformation of cyclobutane is slightly folded. Folding gives partial relief from the eclipsing of bonds, as shown in the Newman projection. Compare this actual structure with the hypothetical planar structure. Draw the relevant structures. 8. trans-1,2-Dimethylcyclobutane is more stable than cis-1,2-dimethylcyclobutane, but cis-1,3- dimethylcyclobutane is more stable than trans-1,3-dimethylcyclobutane. Use the molecular models to find the reasons for...
