How can a compound having a plane of symmetry be Chiral?

WebChirality is a property based on the symmetric elements of an object. For example, if an object is not perfectly symmetrical around the center point, and although if rotated 180 degrees, it might show a mirror image but isn’t completely identical to the original form of the object, then it is a chiral object.
