Question

If two different 3D arrangements in space of the atoms in a molecule are interconvertible merely by free rotation about bonds, they are called _____

• A. Conformational Isomer
• B. Configurational Isomer
• C. Strucutral Isomer
• D. Otical isomerism

Answer 1

The correct option is A Conformational Isomer

If two different 3D arrangements in space of the atoms in a molecule are interconvertible merely by free rotation
about bonds, they are called conformational isomer. Each possible structure is called a conformer. So, the correct answer is option (a).
