Concept explainers
(a)
Interpretation: A plane of symmetry for the given molecule is to be drawn.
Concept introduction: Optical activity of a molecule is the interaction between molecule and plane-polarized light. Molecule having asymmetric center shows optical activity except meso compounds. Asymmetric center is a stereocenter which arises in hydrocarbons if the carbon is bonded to four different groups.
A compound with asymmetric centers possesses a plane of symmetry, so it is superimposable on its mirror image, thereby the compound is achiral.
