With respect to the conformers of ethane, which of the following statements is true?

  1. A
    Bond angle remains same but bond length changes
  2. B
    Bond angle changes but bond length remains same
  3. C
    Both bond angle and bond length change
  4. D
    Both bond angles and bond length remains same

Solution & Step-by-step Explanation

Conformers are different spatial arrangements of atoms that result from rotation about single bonds. This rotation does not change the actual connectivity, the bond angles (approx. ), or the bond lengths ( and ). Only the dihedral angle (angle between bonds on adjacent carbons) changes.
