Why are esters compounds also called derivatives of carboxylic acid?
Not all esters are derivatives of carboxilic acid, they could also be derivatives of phosphoric, sulphuric or carbonic (etc.) acids. However, they are called derivatives of 'X' acid because they are formed by reacting an oxoacid ('X') with a hydroxyl compound (alcohol or phenol). See the related link and related question for more information about how esters are synthesized.
What is difference between a carboxylic acid an ester and an amine?
Esters and amides are derivatives of carboxylic acids. Amines are alkylated derivatives of ammonia: carboxylic acid= R-COOH ester= R-COOR amide=R-CONH2 amine= R-NHR
How does the oxidation of carboxylic acids affect their chemical properties and reactivity?
The oxidation of carboxylic acids increases their reactivity and changes their chemical properties by converting them into more reactive compounds called carboxylic acid derivatives, such as esters, anhydrides, and amides. This process can alter the acidity, solubility, and stability of the carboxylic acids.
What organic compound group are esters in?
Esters belong to the functional group known as carboxylates. They are derived from carboxylic acids and alcohols through a condensation reaction, resulting in the formation of a carbonyl group bonded to an oxygen atom.
Why is O-H stretch not present in an ester?
Because esters are alkyl derivatives of carboxylic acids so they don't have bond between O and H. as CH3-COOCH3
How do carboxylic acids and esters differ in odor?
Carboxylic acids usually have a strong, pungent odor, often described as sour or vinegar-like. Esters, on the other hand, have a sweet, fruity smell. This difference in odor is due to the functional groups present in each compound.
Water and esters are the products of reaction between alcohols and?
Water and esters are the products of the reaction between alcohols and carboxylic acids. This reaction is known as esterification. Alcohols react with carboxylic acids in the presence of an acid catalyst to form an ester and water as byproducts.
Are fats acid ketones ethers esters or alcohols?
Fats are esters of fatty acids and glycerin (propane-1,2,3-triol).
Does esters have carbonyl?
Yes they have if they are esters of Carboxylic acids. Eg: Methyl acetate has carbonyl in its middle : H3C-(C=O)-O-CH3
How do carboxylic acids and esters differ in odor in chemical structure?
Carboxylic acids typically have a sour or rancid odor due to the presence of the carboxyl group, which is responsible for the acidic properties. Esters, on the other hand, have more pleasant and fruity odors because of their structure, which is derived from a carboxylic acid and an alcohol. The ester functional group gives rise to these more desirable scents.
Why methyl esters are not suitable as derivative for carboxylic acids?
methyl esters have very low melting points and they are volatile. so there melting points are difficult to obtain.
What elements are considered as hydrocarbon derivatives?
Hydrocarbon derivatives include compounds that contain carbon and hydrogen atoms, but also other elements such as oxygen, nitrogen, halogens (fluorine, chlorine, bromine, iodine), sulfur, and phosphorus. Examples of hydrocarbon derivatives include alcohols, ethers, aldehydes, ketones, carboxylic acids, esters, amines, amides, halogenated hydrocarbons (such as chloroform), thiols, and thioketones.
