Esters

=//__ESTERS__// = = = = Definition a compound that two hydrocarbon chains attach to a COO group = Examples // ** 1. Oil of Wintergreen 2. Aspirin 3. Triglyceride (glycerol ester with long chain fatty acids ( palmitic 16C))

=// REFERENCE //= //[] //

=How to name an ESTER? = = Position hydrocarbon hydrocarbon connects = = connects to the C side to the O side = = = = Naming "e"-->"oate" p bu tanoate = = arent chain = = = = Example butane-->buta methyl = = noate = = = = (CH3-CH2-CH2-COO-CH3) = = Full name methyl butanoate = CH3-CH2-CH2-CH2-COO-CH2-CH2-CH2-CH3 butyl pentanoate CH3CH2COOCH2CH3 ethyl propanoate
 * ex.** HCOO-CH2-CH2-CH3 propyl methanoate

= **PROPERTIES OF ESTERS** = =**// organic acid + alcohol --> esters + water //**= //** ex. ethanoic acid + methanol --> methyl ethanoate + H2O **// =-- solubility= =-- melting and decompositions temperatures= =-- surface tention=
