Options

A. all are in molecular plane
B. two in molecular plane and one in a plane perpendicular to molecular plane which contains `C-Csigma`-bond
C. one in molecular plane and two in plane perpendicular to molecular plane which contains `C - Csigma`-bond
D. two in molecular plane and one in a plane perpendicular to molecular plane which bisects `C-Csigma`-bond at right angle

Answer

B

Explanation

Nodal plane of `C_(1)-C_(2)` and `C_(3)-C_(4)` in molecular plane.
