Chemistry 11: Organic Chemistry
Last Class, We Discussed:



Alkyl halides: branches of group 7 atoms (Naming rule: fluoro-, chloro-, bromo-, and
iodo-)
Alcohols: molecules containing a hydroxyl group (R-OH) (Naming rule: drop the -e,
add -ol)
Aldehydes molecules wih a C=O (carboxyl group) on an end of the molecule
(Naming rule: drop the -e, add –al)
Ketones
Ketones look similar to ___________________ as we saw yesterday. They both contain the same
______________________________________group.
The main difference is that ketones have the carbonyl group ___________________ along the
parent chain except the ___________________.
If the carbonyl group is on an end of the molecule, we have an ___________________,not a
ketone!
Naming Ketones
We first look at our longest chain (i.e. parent chain)
_________________________________________________________. Then, we drop the_________ from the
suffix, and add ______________. Finally, we add the number of the ________________________________
carbon in front of the name.
The remainder of the molecule is named following the steps as we have seen already.
___________________groups take priority over ___________________ groups!
Examples
Amines vs. Amides
Amines
Amides
Draw Above
___________________contain a
___________________atom within
the molecule.
Draw Above
___________________contain a
___________________ as well as a
___________________.
Naming Amines
___________________
___________________
___________________
Amine naming is different!
2
Naming Amines (Cont’d)
Name the hydrocarbon groups attached to the
_________________________________________________________all ending with __________.
Use _____________ instead of the carbon number to label these groups
______________________________________
If ___________________is a branch, it is called an ___________________ branch
Examples
3
Naming Amides


Name the longest chain containing the ___________________ group giving it
___________________ ___________________.
Drop the____________and add ___________________.
Examples
Draw:
a. Ethanamide
b. 3-ethyl-2,2-difluorooctanamide
c. 4-propyl-2-nonenamide
The remaining time is yours to review and complete the worksheets or your
project
I will go over several questions from past and current worksheets
