Question

explain the optical of 2-chlorobutane​

Answer 1

Answer:

2-chlorobutane is an optically active molecule. the carbon numbered as 2in the molecule is chiral as it has different substituents [-c2h5, ch3, H, Cl] attached to it. thus it rotates plane polarised light in different directions giving rise to two enantiomers [R, S] of the compound.

Answer 2

2-chlorobutane has one chiral carbon atom. The spatial arrangement of the four different groups around the chiral atom is different. 2-Chlorobutane cannot superimpose perfectly on its mirror image as shown in the figure. Hence, 2-chlorobutane exhibits optical isomerism.
