chiral compounds

Question 1

fill in the gap :

chiral compounds are … - ………….. on their mirror image

Answer 1

chiral compounds are NON- SUPERIMPOSABLE on their mirror image

Question 2

define optical isomerism

Answer 2

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.

Question 3

define enantiomers

Answer 3

molecules which are non-superimposable mirror images of one another.
Enantiomers have different effects on a plane of polarised light

Question 4

define racemic Mixture ( or racemate)

Answer 4

a mixture containing equal amounts of enantiomers

Question 5

define chiral carbon

Answer 5

an asymmetric carbon atom/ a carbon atom bound to 4 different groups. This
may also be called a chiral centre.

Question 6

define chirality

Answer 6

(form of stereoisomers)

atoms are joined in the same order but they have different spatial arrangement

Question 7

name one type of chiral compounds

Answer 7

amino acids

Question 8

give 5 characteristics of chiral compounds

Answer 8

non superimposable

mirror images

enantiomers

form of stereoisomers

carbon atom with 4 different groups attached

Question 9

how does optical isomers rotate around polarised light differently

Answer 9

one rotates clockwise the other rotates anticlockwise
