chiral compounds Flashcards
fill in the gap :
chiral compounds are … - ………….. on their mirror image
chiral compounds are NON- SUPERIMPOSABLE on their mirror image
define optical isomerism
a type of stereoisomerism that occurs as a result of the presence of a
chiral centre in a molecule. Optical isomers have different effects on a plane of polarised
light.
define enantiomers
molecules which are non-superimposable mirror images of one another.
Enantiomers have different effects on a plane of polarised light
define racemic Mixture ( or racemate)
a mixture containing equal amounts of enantiomers
define chiral carbon
an asymmetric carbon atom/ a carbon atom bound to 4 different groups. This
may also be called a chiral centre.
define chirality
(form of stereoisomers)
atoms are joined in the same order but they have different spatial arrangement
name one type of chiral compounds
amino acids
give 5 characteristics of chiral compounds
non superimposable
mirror images
enantiomers
form of stereoisomers
carbon atom with 4 different groups attached
how does optical isomers rotate around polarised light differently
one rotates clockwise the other rotates anticlockwise
