Which of the following molecule does not have a plane of symmetry?
Open in App
Solution
The correct option is D
When a molecule is bisected into two equal halves by an imaginary plane then the molecule is said to possess plane of symmetry.
In the given molecule (a), (b) and (d) have a plane of symmetry because they have a imaginary plane shown as a dotted line in the below figure which bisects them into two equal halves.
Molecules possess plane of symmetry:
In compound (c), the imaginary plane does not give equal halves because in this compound one methyl group comes out of the plane and one goes backside of plane.
Therefore, compound (c) does not possess a plane of symmetry.
