Which of the following is optically inactive?
1
2
3
4 None of these
Explanation:
(C) : is optically inactive because it have plane of symmetry. Plane of symmetry an imaginary line passing through a molecule. Bisecting molecule in two equal part which is mirror image to each other is said to be plane of symmetry denoted by ' $\sigma$ '.
