Chirality

Question 1

What is a constitutional isomer

Answer 1

Isomers which have the same formula but different atomic arrangement

Question 2

What is a stereoisomer

Answer 2

Isomers which have the same molecular formula but different spatial arrangement

Question 3

What is geometric isomer

Answer 3

Cis or z (same side) and trans E (opposite)

Question 4

What is an E and a Z stereoisomers

Answer 4

E is opposite side and Z is the same side

Question 5

What is a stereoisomer

Answer 5

Isomers with the same molecular formula but are non superimposable

Question 6

What is a chiral carbon

Answer 6

A molecule with 4 different groups on it

Question 7

What is D and L isomerism with carbohydrates

Answer 7

The most oxidised c is at the top of the molecule and if the bottom OH is:
- to the left, then its a L isomerism
To the right, then it’s a D isomerism

Question 8

What is the Cahn Ingle pre log rules (r/s)

Answer 8

Ordering groups in order of priority around a chiral carbon. If the order is clockwise its a R isomerism if its left, its an S isomerism.

Question 9

2 Similarities between enantiomers

Answer 9

They have the same physical and chemical properties.
