Generally, ester’s are liquid or low-melting solid; and are lighter than Water.All methyl and ethyl esters are liquid at room temperature. The boiling points of ester’s are much lower than those of acids or alcohols of comparable molecular weights because the association by hydrogen bonding, which is largely responsible for the comparatively high boiling points of acids and alcohols, is
