Ester
reaction of a carboxylic acid with an alcohol or phenol to produce an ester
Esterification reaction
naming of ester:

Physical -properties of COOH and COOR
polar compounds
COOH only can undergo intermolecular hydrogen bondingg
COOH has higher BP than COOR
complete opposite of esterification
Ester hydrolysis
COOH in skin care products; these acids work by removing the outer and older layer of skin cells, revealing the healthier looking new ce;ls underneath
Alpha hydroxy acids
pain relievers that contain carboxylic acid
aspirin, ibuprofen
common naturally occuring esters, contain three ester groups, each with a long C chain. lipids, water-insolouble compounds, present in fats and oils
Triacylglycerols
a colorless inorganic compound of nitrogen and hydrogen, linear, hydronitroggen, pungent odor

Nomenclature of amines IUPAC:
1: parent chain attached to N
2: changing e to amine
3: inidcate the number of C arom attached to N
4: substituents
classification of amides:
depends on substitution of hydrogen to Alkyl group
