Molecules whose mirror image is non-superimposable over them are known as chiral. Which of the following molecules is chiral in nature?
(a) 2-Bromobutane
(b) 1-Bromobutane
(c) 2-Bromopropane
(d) 2-Bromopropan-2-ol
Answers (1)
When the mirror images of molecules are identical and superimposable, the molecules are achiral. Achiral molecules should have a plane of symmetry. When the mirror image of achiral structure is rotated, and the structures can be aligned with each other, their mirror images are called achiral carbon atoms.
Chirality often leads to optical activity in a compound. But, it is not a necessary condition for optical activity. Optical activity is the ability of a molecule to rotate plane- polarized light.
Hence, the answer is the option (a).
