![]() ![]() It is used as a solvent for the preparation of medicines and other pharmaceutical products. It is primarily used as a solvent because of its low cost, low toxicity, and fruity odor.Ethyl acetate is synthesized from acetic acid and ethanol by the process of esterification in the presence of an acid.Ethyl acetate or ethyl ethanoate is an ester with the molecular formula CH 3 -COO-CH 2 -CH 3.Some examples of ethers are methoxy ethane, phenoxy benzene, etc. Some examples of esters are methyl acetate, ethyl propionate, etc. The boiling point of ethers is even lower than the esters, carboxylic acids, and alcohols of the same weight.Įsters do not have symmetrical structures due to the presence of a carbonyl group.Įthers can be symmetrical if the alkyl and aryl groups bonded to the oxygen atom are similar.Įsters are commonly used in the food industry to enhance the taste and odor of the product.Įthers are commonly used in drugs as solvents. The boiling point of esters is lesser than the carboxylic acids and alcohols of the same weight. The functional group in ether is –O- which is also called the alkoxy group.Įsters are provided with the suffix ‘-ate’ according to IUPAC rules.Įsters are derived from carboxylic acids.Įsters are more polar than ethers due to the presence of the carbonyl group. The functional group in ester is –COO- which is also called the ester group. The chemical formula of the ester is RCOOR’. The most popular method of synthesis of ethers is via the Williamson ether synthesis.ġ2 Key Differences (Ester vs Ether) Characteristics Ethers can be prepared artificially by the dehydration of alcohols and alkyl halide.The ability of ethers to be used as solvents due to the possibility of the formation of hydrogen bonds with other molecules.Ethyl ether, in particular, is used as an excellent solvent for the extraction of various chemicals.Different ethers have different applications in various industrial fields as some are essential in medicine and pharmacology for the preparation of anesthetics.These occur in the form of pleasant-smelling colorless liquid. Ethers usually have a lower boiling point and are less soluble than the respective alcohols.Based on the IUPAC nomenclature system, ethers are named by the general formula, ‘alkoxyalkane’.Ethers are more acidic than simple hydrocarbons as well as esters, as the oxygen atom is more electronegative than carbon.The C-O linkage in ethers is bent, usually at an angle of 111°, and the bond is flexible for rotation.If the same alkyl or aryl groups are present, it is a simple or symmetrical ether, but if the groups are different, the ethers are called mixed or asymmetrical ethers.Ethers can be broadly classified as symmetrical and mixed or asymmetrical ethers depending on the type of alkyl or aryl groups present on the sides of the oxygen atom.The chemical formula of ether is R-O-R’.Esters also occur in fats in the form of trimesters which are essential for the structure and energy of living systems.Įther is a group of organic compounds consisting of the ether group -O- connecting two alkyl or aryl groups.Esters are mostly used in food industries for the incorporation of the aroma of many fruits like apples, bananas, pears, etc.The presence of the carbonyl group also increases the polarity of the compound as the charge developed can be distributed to the carbon and oxygen to generate a stable structure.The flexibility of the angles allows for certain physical properties of the compounds, like lower melting point and increased volatility.Due to the presence of a carbonyl center, esters have 120° C-C-O and O-C-O angles, and the functional groups of these esters are flexible.Esters are named with the suffix ‘-ate’ by the IUPAC. Esters contain a carbonyl group which is then attached to an oxygen atom to form the functional group. ![]() The process of formation of esters is called esterification, which is the reaction between carboxylic acids and alcohols in the presence of acid.The chemical formula of esters is RCOOR’, where the R and R’ can be the same or different organic groups.Esters are essential organic compounds that form the structural basis of essential biomolecules like lipids.The functional group in ester is the ester group (COOR) which is usually formed as a result of a substitution reaction between carboxylic acids and organic alcohols.An ester is a group of organic compounds that are derived from organic acids where at least one –OH group is replaced by an -O- group. ![]()
