Problem 27P
Draw the two chair conformations of each of the following substituted cyclohexanes. In each case, label the more stable conformation.
(a) cis-1-ethyl-2-methylcyclohexane (b) trans-1,2-diethylcyclohexane
(c) cis-1-ethyl-4-isopropylcyclohexane (d) trans-1-ethyl-4-methylcyclohexane
ANSWER:
Solution 27P :
Step 1:
Here, we have to draw the two chair conformations for the given cyclohexane and label the most stable conformation among them :
Cyclohexane is a cycloalkane. Cycloalkanes are the alkanes having rings of carbon atoms. It has molecular formula of C6H12.
Conformation is nothing but a shape or structure of the compound. Conformations are the structures of the compound. They are the different positions of a molecule that it can bend into. Atoms and bonds remain the same on the molecule in the conformation, the only variation is the angles in which certain parts of molecule would be bent or twisted.
Among the chair conformations, we determine the stability of the conformation by the placement of larger groups on the type of bond. Generally, the most stable chair conformation is the conformation that has the larger groups placed on the equatorial bond.
