Read the passage given below and answer the following questions: The objects which are non-superimposable on their mirror image (like a pair of hands) are said to be chiral and this property is known as chirality. Chiral molecules are optically active, while the objects, which are, superimposable on their mirror images are called achiral. These molecules are optically inactive. The above test of molecular chirality can be applied to organic molecules by constructing models and its mirror images or by drawing three dimensional structures and attempting to superimpose them in our minds. There are other aids, however, that can assist us in recognising chiral molecules. One such aid is the presence of a single asymmetric carbon atom. In these questions a statement of assertion followed by a statement of reason is given . Choose the correct answer out of the following choices. Assertion (A): Butan-2-ol is a chiral molecule. Reason (R): It has 4 different groups attached to carbon atom.
