(a)
To determine: The plane of symmetry if the molecule has an internal plane of symmetry and if the structure is chiral on absence of plane of symmetry.
Interpretation: The validation of the statement that the given molecule contains a plane of symmetry is to be stated and on absence of plane of symmetry, the chirality of the molecule is to be detected.
Concept introduction: A carbon which has all the four different atoms or group of atoms show tetrahedral geometry is referred to as the chiral carbon. The mirror image of an object that contains chiral carbon has non-super imposable mirror image. The two different forms in which a single chiral carbon can exist is referred to as enantiomers. The number of enantiomers of a molecule depends on the number of chiral centres.
