The given compound 1,3-dichloropentane is optically active .
Because this compound does not have plane of symmetry (POS) and center of symmetry (COS) . And also forms non superimposable mirror image . the compound is optically active .
It has chiral center.
Here , the chiral carbon is bonded to 4 distinct groups such as : hydrogen , ethyl , chloroethane , and chlorine .
What is plane of symmetry?
A compound when we cut it into through a plane then if the two halves are superimpossable to each other then the compound have plane of symmetry.
Chiral center :
Have Sp3 hybridized center (4sigma bond ) .
4 distinct group is attached to the chiral atom. form non -superimposable mirror image .
What is optical isomerism ?
Same molecular formula and same structural formula . also have same physical and chemical properties .
They shows different behavior towards plane polarized light.
