Chemistry - STEREO ISOMERISM Question with Solution | TestHub
A plane of symmetry is an imaginary plane that bisects a molecule into halves that are mirror images of each other. Center of symmetry of a molecule is the center point from which the identical atoms exist on the opposite side from this center at equal distance
Which of the following molecule contains centre of symmetry?
Options:
Answer:
Solution:
Option (C) contains a center of symmetry ().
Definition: A center of symmetry exists when moving from any atom through the central point leads to an identical atom at an equal distance.
Option A: Both bromine atoms are on the same side (cis), so they do not invert into each other through the center.
Option B: The cumulative double bonds force the terminal groups into mutually perpendicular planes, preventing inversion symmetry.
Option C: The opposite carbonyl () groups and the trans-arranged and atoms perfectly balance across the ring's geometric center.
