Concept explainers
Interpretation:
The reason for the lack of optical activity in the 2-chlorobutane after it is examined with a polarimeter is to be explained.
Concept introduction:
Enantiomers are one of the two molecules that are a mirror image of each other and are non-superimposable.
The ability of certain substances to rotate the plane of a plane-polarized light as it passes through a crystal, a liquid, or a solution is known as optical activity.
The rotation of the polarized light could be in clockwise or counterclockwise direction.
If the rotation of the polarized light will be in clockwise, it is dextrorotatory.
If the rotation of the polarized light will be in counterclockwise, it is leavorotatory.
If both the enantiomers are present in same amount, then it is optically inactive.
A scientific instrument thatis used to measure the angle of rotation caused by passing the polarized light through an optically active substance is known as a polarimeter.
