Naming of esters:
O || C - CH3 / CH3 - CH2-O
ethyl acetate/ethanoate (comes from (comes from the alcohol) the acid)
Esters can participate in hydrogen bonds as hydrogen bond acceptors, but cannot act as hydrogen bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonds leads them to be more water soluble than their parent hydrocarbons. But the limitations on their hydrogen bonding also make them more hydrophobic than either their parent alcohols or parent acids. Their lack of hydrogen-bond donating ability means that they can't form hydrogen bonds between ester molecules, which makes them generally more volatile than an acid or ester of similar molecular weight.
Many esters have distinctive odors, which leads to their widespread use as artificial flavorings and fragrances. For example:
Esters also participate in ester hydrolysis - the breakdown of an ester by water. Esters may also be decomposed by strong acids or bases. As the result they are decomposed into an alcohol and a carboxylic acid, or a salt of carboxylic acid
