stereochemistry

Question 1

stereochemistry

Answer 1

where the atoms are joined in the same order but they have a different arrangement in space

Question 2

2 types of stereochemistry

Answer 2

geometric and optical

Question 3

geometric isomers

Answer 3

occurs in molecules containing a C=C, no free rotation around the pi bond so atoms are fixed in space

Question 4

cis and trans isomers

Answer 4

are different compounds and have different properties

Question 5

optical isomers

Answer 5

when 4 different atoms are arranged around a single atom the molecule can exist in two isometric forms and these isomers are non superimposable mirror images of each other

Question 6

chiral centre

Answer 6

a central carbon which has 4 different groups attached

Question 7

optical isomer properties

Answer 7

identical both in their physical and chemical properties and they differ in the way they affect plane polarised light as one will rotate polarised light to the right and the other to the left

Question 8

racemic mixture

Answer 8

mixtures which contain equal amounts of both optical isomers and the isomers rotate polarised light in opposite directions so are optically inactive
