Question

Which of the following cyclopentane derivatives has plane of symmetry?

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

A symmetry element is a point, plane or a line of reference about which symmetry operations can be done.
E.g: Symmetry elements can be mirror planes and the centre of inversion.

If an identical copy of atoms in one side of the plane is generated with its corresponding side as a mirror image, the molecule is said to have a Plane of Symmetry.

Here, compound (b) has plane of symmetry
