Esters (p. 49) • Organic compound formed by the condensation reaction of a carboxylic acid and an alcohol. • O O R-C-OH + R-OH R-C-O-R’ + H2O (ester)
Esters (p. 49) O R-C-O-R’ • Naming: • Parent chain “R” (including the C bonded to the oxygens) • Name the parent as an alkane • Take off the “e”. • Add –oate • Branches • Identify alkyl group, R’ • Add alkyl name in front of parent chain.
Example O C-C-O-C-C-C Parent: ethane ethanoate Branch: propyl Final name: propylethanoate
Example O C-C-C-C-O-C-C- Parent: butane butanoate Branch: ethyl Final name: ethyl butanoate
Draw: pentylhexanoate O C-C-C-C-C-C-O-C-C-C-C-C
Name: O C-O-C-C-C Parent: propane propanoate Branch: methyl Final name: methyl propanoate
Amines (p. 51) • Organic compounds that are derivatives of ammonia (NH3 ). R-N-R” R’ • Naming: • Name the branches (R, R’, R”) in alphabetical order; they can also be halogens. • Add the word amine at the end.
Primary amine • (1 hydrogen is replaced by an alkyl group) C-N-H H • methyl amine
Secondary amine • (2 hydrogens are replaced by alkyl groups) C-N-C-C H • ethyl methyl amine
Tertiary amine • (3 hydrogens are replaced by alkyl groups) C-N-C-C C-C-C • ethyl methyl propyl amine
Draw: pentylpropyl amine C-C-C-C-C-N-C-C-C H
