WebCorrect option is A) A chiral centre is an atom that has four different groups bonded to it in such a manner that it has a non superimposable mirror image. No. of chiral centres =3. … WebThe center C has 4 C atoms attached to it, but it is still a chiral center because each of the C atoms it is bonded to is itself bonded to different atoms. In general a molecule with a chiral center will have non-superimposable mirror image. These mirror image molecules are called enantiomers or in older notation optical isomers.
