Transcript Unit 7B Esters and Amines PPT

Esters (p. 37)
 Organic compounds that began as acids and were
reacted with alcohols to become esters.
 General form:
O
R- C-O-R
 R with C=O is parent chain.
 R connected to –O is alkyl branch.
Naming:
 Parent
Chain
 The part connected to the double bonded
oxygen (that is carbon #1)
 It is named last
 Name as an alkane (remove the “e”)
 Ends in –oate (pronouced “o” ate)
Naming:
 Branches
 Named first
 Part connected to the single bonded oxygen
 End in –yl


Example: Propyl ethanoate

Amines (p. 39)
 Organic compounds based on NH3
 General form:
R”
R- N -R’
 Naming:
 Carbon
branches ( -yl) replace hydrogens
 Put in alphabetical order
 Add amine at the end
Amine Types
 Primary
 One hydrogen is replaced with an alkyl group
 Secondary
 Two hydrogens are replaced with an alkyl group
 Tertiary
 Three hydrogens are replaced with an alkyl group
Example: Name

C - C - C – C – N - C – C – C – C –C
Butyl nonyl pentyl amine
Example:
C–C–N-C-C
