Is alkyl benzoate ionic or covalent?
Alkyl benzoate is a covalent compound. It is formed by the sharing of electrons between the carbon and oxygen atoms in the ester functional group.
Which shows the general structure of an ester?
B.
What is the key difference between ether and ester in terms of their chemical structures and properties?
The key difference between ether and ester lies in their chemical structures. Ethers have an oxygen atom bonded to two alkyl or aryl groups, while esters have an oxygen atom bonded to an alkyl group and a carbonyl group. Ethers are typically less reactive than esters and have lower boiling points. Ethers are commonly used as solvents, while esters are often found in fragrances and flavorings.
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 an alkyl phosphate?
An alkyl phosphate is a chemical compound consisting of a phosphate group bonded to an alkyl group. These compounds are widely used in various applications, including as surfactants in cleaning products and as flame retardants in plastics.

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.
Is ch3conh2 an ester?
No. The general formula for an ester is R-COO-R', where R and R' are organic groups. R can be a hydrogen, but if R' is hydrogen (as it is in this example) then the compound is a carboxylic acid.
What is the difference between malonic ester synthesis and acetoacetic ester synthesis?
The Malonic Ester Synthesis begins with the dimethyl ester of a malonic acid (a beta-carboxy ester). This reaction is used to make substituted CARBOXYLIC ACIDS.1. You start with malonic ester (a beta-carboxy ester) and alkylate it with an alkyl halide. This step is what attaches the alkyl group from the alkyl halide to the malonic ester at the position beta to both carbonyls.2. You then add water and strong base to hydrolyze the ester groups at the ends into carboxylic acid groups, giving you malonic acid (a beta-diacid). It looks like the product from the first step, only there are carboxylic acids in place of the esters at both ends.3. Upon gentle heating, a CO2 leaves giving the enol. The enol tautomerizes, meaning it introconverts into its isomer, the carboxylic acid. The carboxylic acid contains that R group that we attached during step 1.The Acetoacetic Ester Synthesis has a different starting material, but follows the same Akylation-Hydrolysis-Decarboxylation steps! It is used to make asymmetrical, substituted KETONES.1. You start with acetoacetate (a beta-keto ester) and alkylate it with an alkyl halide. This step is what attaches the alkyl group from the alkyl halide to acetoacetate at the position beta to both carbonyls.2. You then add water and strong base to hydrolyze the ester group into a carboxylic acid, giving you a beta-keto acid. It looks like the product from the first step, only there's a carboxylic acid in place of the ester at the end.3. Upon gentle heating, a CO2 leaves giving the enol. The enol tautomerizes, meaning it introconverts into its isomer, the ketone. The ketone is unsymmetrical due to that R group that we attached during step 1.
Who gives oxygen atom in ester synthesis?
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 type of compound is formed when an alcohol reacts with an inorganic acid such as phosphoric acid?
When an alcohol reacts with an inorganic acid like phosphoric acid, the result is the formation of an ester. Ester formation involves the substitution of the -OH group of the alcohol with an -OR group from the acid, creating a compound that has a carbonyl group (C=O) bonded to an oxygen atom and an alkyl (or aryl) 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 is the general formula of ester?
The general formula of an ester is RCOOR', where R and R' represent alkyl or aryl groups. It consists of a carbonyl group (C=O) bonded to an oxygen atom, which is in turn bonded to another carbon atom. Ester groups are commonly found in fats, oils, and many fragrant compounds.
