Nomenclature Questions

Question 1

How you distinguish between two seperste samplws of the two enantiomers of the branched chain aldehydes c5h10o

Answer 1

Use plane polarised light
Rotates the plane in opposite directions

Question 2

Explain the differences between structural and stereoisomerism

Answer 2

Structural where molecules with same molecular formula but different structure whereas stereoisomers where molecules with the same structural formula but diffeeemr arrangement of atoms in space they also have lack of rotation around c=c

Question 3

How many isomers in c3h9n

Answer 3

4

Question 4

Name a species that can act as a nucleopjile

Answer 4

Ch3oh

Question 5

How many structural isomers are there with the molecular formula c3h6brcl

Answer 5

5

Question 6

Explain how cip priority rules can be used to deduce the full iupac name of this compound

Answer 6

1)consider the groups joined to right hand carbon of the c=c bind
2)consider the atomic number of the atoms attached
3)higher atomic number takes a higher priority
4)consider groups on LH of c=c bond
5)deduce if it’s e or Z isomer - if high priority groups are on same side
