Carbon-based molecules can have different spatial orientations called conformations(构象) Fig 12.2 three conformation for a molecule of n-pentane. the molecule looks different in each conformation but the five-carbon framework is the same in all three conformations In a sample of liquid n-pentane the molecules are found in all conformations-not unlike a bucket of wormsCarbon-based molecules can have different spatial orientations called conformations (构象).
