Build models of the structures of cis- and trans-1,6- di-tert-butyidecalin (see section 4.15).

The hydrindanes exist in cis and trans- diastereomeric forms. … Each six membered ring will adopt a chair conformation. Believe it or not, the cis and trans stereoisomers of decalin have remarkably different shapes. There’s no better way to see this than by making a model. 2. A Model Of cis -Decalin Shows It Has A Tent-Like Shape Here’s cis -decalin. See more The parent molecule is called “decalin” since there are ten carbons in total. However, remember that any time we have two substituents on a cyclohexane ring (as we do here), it is essential to draw in the … See more Here’s cis-decalin. The hydrogens on the “bridgeheads” are highlighted in red and white. Notice how both cyclohexanes are in chair conformations, but the molecule adopts almost a tent-like shape. via GIPHY See more As these movies show, changing the stereochemistry of the bridgehead carbon from a “wedged” H to a “dashed” H can make a huge difference in the overall shape of the … See more And here’s trans-decalin. As we look at the molecule from an angle, it’s obvious that both cyclohexane rings are also in the chair conformation, but the molecule is much flatter overall. via GIPHY See more can\u0027t smell with a cold
