In the next chapter we'll look at cycloalkanesâ€”saturated cyclic hydrocarbonsâ€”and weâ€™ll see that the molecules generally adopt puckered, nonplanar conformations. Cyclohexane, for instance, has a puckered shape like a lounge chair rather than a flat shape. Why?

Butanal (C4H&O) has eight H atoms. Suppose that any of these H atoms can be replaced by a Cl atom to yield a molecule with the formula C4H¬CIO. (a) Identify two H atoms where this substitution would yield constitutional isomers of C4H7CIO; (b) enantiomers of C4H;CIO; (c) conformers of C4H;CIO. H. H H H нн H Butanal O=U
Perspective drawings of Chair and Boat Conformers fo Cyclohexane (C6H12). Note it is impossible to place all the carbons in the same plane without straining the bonds. Take two opposite carbons and pull both of them up to make one conformation adn then pull one of them down to make the other conformation. Can you inercovert one conformer int othe other without breaking any bonds? Explain why these represent conformers and not isomers.
