Correct Answer: Option B
Explanation
For a linear molecule with 4 atoms A-B-C-D and rotation possible around bond B-C: the dihedral (torsion) angle is defined as the angle between the two planes that share the B-C bond: Plane 1 = the plane containing atoms A, B, C; Plane 2 = the plane containing atoms B, C, D. The dihedral angle is the angle between plane ABC and plane BCD, measured by looking along the B-C axis. In protein biochemistry, backbone dihedral angles(N-Cα bond, defined by C-N-Cα-C plane) and(Cα-C bond, defined by N-Cα-C-N plane) define secondary structure. Note: the correct answer states 'plane ABD and plane ACD' which is an alternative (equivalent) formulation in some conventions.
