Optical Isomerism

Question 1

Optical Isomerism

Answer 1

Form of stereoisomerism occurring as a result of chirality in molecules

Question 2

Chiral Carbon

Answer 2

Carbon in a compound with 4 different groups attached to it

Question 3

Optical isomers of Alanine

Answer 3

Enantimors

Question 4

Racemic Mixture

Answer 4

50/50 mixture of two enantimors

Question 5

Properties of enantimors

Answer 5

Have an effect on plane polarised light
React wit other chiral carbons

Question 6

Describe how separate samples of each enantiomers could be distinguished

Answer 6

Shine plane polarised light through the sample, the light would rotate in the opposite direction

Question 7

Why are racemic mixtures optically inactive?

Answer 7

The two enantiomers cancel each others light rotating effect

Question 8

How is a racemic mixture formed (racemate)?

Answer 8

C=C and C=O double bonds are planar, the products of the reactions that occur at the carbonyl group of aldehydes and ketones are enantiomers present as a racemic mixture

Question 9

What mechanism creates optically active compounds?

Answer 9

Nucleophilic Addition
