Isomerism concept?

Question

What is the main concept of optical isomerism? or Which things needed to remember when study optical isomerism in organic chemistry?

Answer 1

A molecule is chiral when it cannot be superimposed on its mirror image with the two mirror image forms referred to as enantiomers. The two "hands" (enantiomers) of a chiral molecule are sometimes referred to as optical isomers. The term optical activity derives from the interaction of chiral materials with polarised light. A solution of the (−)-form of an optical isomer rotates the plane of polarization of a beam of plane polarized light in a counterclockwise direction, vice-versa for the (+) optical isomer.

For example dextroamphetamine will bend a plane of light to the right, where levoamphetamine will bend light to the left and they have very different properties even though they are isomers of the same chemical formula.

Answer 2

hmm i even have this question on my lab paper :D i think of this is as a results of fact the chemist would decide to comprehend if the compound has a similar volume of molecules interior the compound. although, there are various techniques for a compound to be familiar, so there are various possibilites. the scientist ought to differentiate and take care of the compounds. the scientist ought to seek for a similar volume of molecules interior the compound, yet in distinctive structures.
