It depends on which reaction is used to create the ester. When catalyzing a carboxylic acid with a strong base such as NaOH, then using an alkyl halide, the oxygen is from the acid.
R-COOacidH + NaOH -> R-COO-acid + R'X ->R-COOacidR'
When using a carboxylic acid with an alcohol or an acid chloride with an alcohol, the oxygen originates from the alcohol.
R-COOacidH + R'OalcoholH + HCl -> R-COOalcoholR'
R-COOacidCl + R'OalcoholH + Pyridine -> R-COOalcoholR'

What is the minimum number of oxygen atoms present in an ester?
The minimum number of oxygen atoms present in an ester molecule is one. This oxygen atom is typically part of the carbonyl group within the ester functional group.
What is the minimum number of hydrogen atoms present in a carboxylic ester?
The minimum number of hydrogen atoms present in a carboxylic ester is two: one hydrogen atom attached to the oxygen in the ester functional group and one hydrogen atom on the carbon atom adjacent to the ester group.

What functional group is in ethyl butyrate?
The functional group in ethyl butyrate is the ester functional group, which consists of a carbonyl group bonded to an oxygen atom, C=O-O-R. In ethyl butyrate, the R group is an ethyl group.
What is the name of an An organic compound in which the hydrogen atom of a carboxyl group is replaced by a carbon atom?
ester
Between what two atoms do ester bonds occur?
Ester bonds occur between a carbon atom and an oxygen atom. Specifically, the bond is formed between the carbonyl carbon of a carboxylic acid and an oxygen atom of an alcohol in an esterification reaction.
What is the minimum number of oxygen atoms present in an ester?
The minimum number of oxygen atoms present in an ester molecule is one. This oxygen atom is typically part of the carbonyl group within the ester functional group.
What is the difference between an ether linkage and an ester linkage in organic chemistry?
An ether linkage is a bond between an oxygen atom and two carbon atoms, while an ester linkage is a bond between an oxygen atom and a carbon atom. Ether linkages are found in ethers, while ester linkages are found in esters.
What is the minimum number of hydrogen atoms present in a carboxylic ester?
The minimum number of hydrogen atoms present in a carboxylic ester is two: one hydrogen atom attached to the oxygen in the ester functional group and one hydrogen atom on the carbon atom adjacent to the ester group.
What are the differences between ether linkage and ester linkage in terms of their chemical properties and biological functions?
Ether linkages are formed by the bonding of an oxygen atom to two carbon atoms, while ester linkages are formed by the bonding of an oxygen atom to a carbon atom and another oxygen atom. In terms of chemical properties, ether linkages are more stable and less reactive compared to ester linkages. In biological functions, ether linkages are commonly found in lipids and cell membranes, while ester linkages are important in the formation of fats and oils.
What is structure of nitrite ester?
A nitrite ester typically has a nitrooxy group (ONO-) attached to a carbon atom in the ester functional group, which is a carbonyl group (C=O) bonded to an alkoxy group (RO-). This structure gives the compound its characteristic reactivity and properties. Nitrite esters are commonly used in organic synthesis and as explosive materials.
What is the difference between an ester linkage and an ether linkage in organic chemistry?
An ester linkage is a bond between a carbon atom and an oxygen atom, while an ether linkage is a bond between two carbon atoms with an oxygen atom in between. Ester linkages are found in esters, which are commonly used in fragrances and flavorings, while ether linkages are found in ethers, which are often used as solvents.
Which oxygen-containing functional group would you find in ethyl acetate?
In ethyl acetate, you would find an ester functional group, which consists of a carbonyl group bonded to an oxygen atom and an alkyl group.
What would you expect the structure of the dinitro ester to be?
A dinitro ester would likely have the nitro groups (-NO2) attached to the ester functional group through single bonds. The structure would contain two nitro groups bonded to the carbon atom in the ester group, each with an oxygen atom attached to a nitrogen atom.
What is ester group?
An ester group is a functional group in organic chemistry consisting of a carbon atom doubly bonded to one oxygen atom and singly bonded to another oxygen atom. It is commonly formed by the condensation reaction between a carboxylic acid and an alcohol, resulting in the loss of a water molecule. Esters are found in fats, oils, and many fragrances and flavorings.
The functional group for ester is?
The functional group for an ester is the carbonyl group (C=O) bonded to an oxygen atom, which is also bonded to another oxygen atom through a single bond (O-C=O). Esters are commonly found in fats, oils, and many fragrant compounds.
Which functional group does not contain oxygen amine alcohol ester ketone?
Amine does not contain oxygen. It is characterized by a nitrogen atom bonded to hydrogen atoms or organic groups.
