Question 19

The various shapes taken on by an organic molecule are known as ________.

Accepted Answer

Conformations refer to the various shapes that an organic molecule can take on due to rotations around single bonds. Constitutional isomers are different molecules with the same molecular formula, preferential isomers is not a commonly used term in organic chemistry, and configurations refer to the spatial arrangement of atoms or groups in a molecule that cannot be changed without breaking a bond.
