Which one of the Following Compounds Shows Optical Activity
3-methyl-1-pentane shows optical activity. It is called a chiral molecule.
Answer - Option C, 3-methyl-1-pentane
The correct answer is 3-methyl-1-pentane. Here all the attached groups to the central carbon atoms are different. There is no plane of symmetry, i.e. it is called a chiral molecule. In 3-methyl-1-pentane there is only one chiral center.
