Front 38

How do you name a structure according to IUPAC?

Back 38

1.) Find the parent chain
2.)Number the chain by giving the substituent the lowest number possible.
3.) give the substituent a name and number.

Front 39

When naming according to IUPAC, what happens if there are two or more identical substituents?

Back 39

1.)Number the chain from the end that gives the lower number to the substituent encountered first.
2.) Indicate the number of times the substituent appears by a prefix like di, tri, tetra, etc.
3.) Use a comma to separate position numbers.

Front 40

When naming according to IUPAC, what do you do when there are two or more different substituents?

Back 40

1.) list them in alphabetical order
2.) number from the end of the chain that gives the substituent encountered first the lower number.

Front 41

True or false:
According to IUPAC, the prefixes di, tri, tetra, etc. are NOT included in alphabetization.

Back 41

True

Front 42

According to IUPAC nomenclature, what happens when there are two or more parent chains of identical length?

Back 42

Choose the parent chain with the greater number of substituents and continue nomenclature from there.
