Carboxylic acids have often not very pleasant smelling.
Esters smell sweeter, often fruity.
This question needs to be more specific - when a carboxylic acid and an alcohol are reacted (usually in the presence of a dehydrating agent, e.g. conc. sulfuric acid), the major product is generally an ester.Esters can have a variety of odours depending on the identity of the carboxylic acid and alcohol. The odour relates to the volatility of the ester, which allows its to be breathed into the nasal passage, and to structural complementarity between the molecule and receptors in the olfactory bulb.I've found a list of common esters and their odours at the bottom of this web page:http://www.3rd1000.com/chem301/chem301v.htmI'm sure that many other sites have more extensive information than this.
Yes, most of smells come from esters which can be derived from carboxylic acids, but they also come from adlehydes, ketones, alcohols, and terpenes. These smells get stronger with the greater amount of carbons in a chain or ring. Low molecular weight esters give fruits their odors and flavors while carboxylic acids have a more acrid and repellent stench. All of this is organic chemistry.
An ester solvent is a type of solvent that is derived from esters, which are organic compounds formed by the reaction between a carboxylic acid and an alcohol. These solvents are commonly used in various industries, such as in paints, coatings, and cleaning products, due to their ability to dissolve a wide range of substances. Ester solvents are known for their low toxicity and pleasant odor compared to other solvent types.
Body odor primarily comes from the interaction of sweat with bacteria on the skin, leading to the breakdown of proteins and lipids. Key components of body odor include fatty acids, ammonia, isovaleric acid, sulfur compounds, and volatile organic compounds (VOCs). These substances can vary based on factors such as diet, hygiene, genetics, and hormonal changes. As a result, individual body odor can differ significantly from person to person.
The odor in sweat is primarily caused by the presence of bacteria on the skin breaking down sweat into acids. These acids can produce a distinct smell, which varies from person to person based on factors like diet, hormones, and overall health. Hormones can also play a role in regulating the amount and type of sweat produced, further affecting body odor.
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.
Some disadvantages of using carboxylic acids include their corrosive nature, potential toxicity, and unpleasant odor. They can also be challenging to handle due to their tendency to form strong acids in solution.
Odor!
Esters give many flowers their pleasant odor.
Normally, the natural odors are made by esters. Bases react with esters and form alcohol and carboxylate ions. So bases can be used to attract onion odor.

Esters have a sweet, fruity smell that is often associated with various fruits. This characteristic odor is due to the presence of ester functional groups in their chemical structure. The pleasant smell of esters contributes to their overall chemical properties by making them useful in flavorings, fragrances, and as solvents in various industries.
Vinegar contains acetic acid. Acetic acid has a sour taste. This gives the odor and the taste to vinegar.

Alcohols are soluble in water (the longer the carbon chain the less soluble it will be) Carboxylic acids are insoluble in water. Hope this helps
Body odor refers to the unpleasant smell that is produced when sweating. Microorganisms, particularly bacteria, cause the offensive smell by breaking the sweat into acids.
