This is a multiple choice answer as classified in NCERT Exemplar
The Correct Answer is Option (i).
The structure of 2-Bromobutane is depicted in the diagram below. Because all of the groups connected to the central carbon atom differ, the mirror image of the molecule cannot be superimposed on the original molecule.
The structure of 1-Bromobutane is shown in the diagram below. Because there are just three groups that vary from one another, the molecule is not chiral in nature.
The structure of 2-Bromopropan-2-ol, shown below, has two identical species and hence cannot be chiral.
