Answer:
(b) May be your answer because 2 dimensional shap
Answer:
(D) CO: It is not clear what shape is meant by "CO." If "CO" refers to the molecule carbon monoxide, then it has a linear shape and a C∞v symmetry. A linear shape has an infinite number of major axes of symmetry, which are any line passing through the center of the molecule.
Explanation:
(A) C2: The major axis of symmetry for a C2 shape is the line that bisects the shape into two equal parts. Since a C2 shape has a rotational symmetry of 180 degrees, the major axis of symmetry is any line that passes through the midpoint of the shape and is perpendicular to the rotational axis. Therefore, there are two possible major axes of symmetry for a C2 shape.
(B) C3: The major axis of symmetry for a C3 shape is the line that bisects the shape into two equal parts and passes through the center of rotation. Since a C3 shape has a rotational symmetry of 120 degrees, there is only one major axis of symmetry.
(C) C: A C shape has rotational symmetry of 360 degrees, which means that it has an infinite number of major axes of symmetry. Any line passing through the center of the C shape is a major axis of symmetry.
(D) CO: It is not clear what shape is meant by "CO." If "CO" refers to the molecule carbon monoxide, then it has a linear shape and a C∞v symmetry. A linear shape has an infinite number of major axes of symmetry, which are any line passing through the center of the molecule.
