The given compound 2,3-dimethyloctane is an optically active compound .
Because this compound does not have plane of symmetry (POS) and center of symmetry (COS) i.e. does not have di-symmetry . And also forms non superimposable mirror image . the compound is optically active .
It has chiral center.
Here there one chiral centers presents , in which the 4 distinct groups (methyl , iso propyl , hydrogen and pentyl ) are bonded .
What is di-symmetry?
Di-symmetry is that which have no center of symmetry and plane of symmetry and alternate axis 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 differ in their behavior towards plane polarized light (ppl) .
