Chiral molecules can be described as ones with a set of stereoisomers or left and right-handed enantiomers. As defined by Lord Kelvin, a molecule has chirality “if its image in a plane mirror, ideally realized, cannot be brought to coincide with itself.” In other words, a chiral molecule is asymmetrical in the sense that it's mirror image will not be an exact copy of itself.
