Let's Define What An Ester Is

The term ester refers to an organic compound derived from carboxylic acid in which the hydrogen atom of the hydroxyl group has been replaced by an alkyl group. The general structure is the product of the union of the function of carboxylic acid (the R group) and the carbon chain that forms the alcohol (the R' group). The general formula of an ester...

Its Aromas

The lower members of the esters of carboxylic acids are colorless, fruit-scented liquids, while the upper members are odorless. With reference to the first ones, different combinations of alcohols and carboxylic acids give rise to different esters, and each ester has a unique aroma. And it is very interesting how with only small differences in the ...

Characteristics and Properties

Esters are polar molecules, which is due to the presence of the C=O group, which gives the polarity to all compounds derived from carboxylic acids. However, their boiling points are lower than those of carboxylic acids and alcohols of similar molecular weight, essentially because there is no intermolecular interaction through hydrogen bridges betwe...

So Why Do Esters Smell So good?

There could really be a great number of reasons or only one, but it is still not entirely clear; it seems to be due to a genetic advantage produced in plants so that certain species eat their fruit; and thus spread the seeds thus allowing new plants to grow and colonize other places. Or it could be the other way around, that animal species have evo...

and How Have Esters Helped The Processed Food Industry?

Our society has a great demand for food, so it is necessary to resort to processed foods to satisfy that demand. Even so, when we buy a canned product we expect this food to have the appearance of a fresh food; but as we mentioned, due to its low boiling point, the esters that naturally give food its aroma are usually lost during processing when th...

What odors do esters have?

Esters tend to have pleasant odors associated with flavoring and scents used in foods, perfumes, personal care products and many other commercial products. We will also be considering two other organic functional groups in this lab, carboxylic acids and alcohols. Carboxylic acids tend to have strong, foul odors.

What odors are found in a chemistry lab?

The odors for the esters in this lab include: banana oil, oil of wintergreen, artificial peach flavor, pineapple oil, orange oil, and an ester that is found naturally in apples, cherries, cheese, brandy and beer. ? Turn off and unplug the hotplate when you are finished. ? Dispose of all chemicals in the proper waste container.

What is an ester derived from?

The term ester refers to an organic compound derived from carboxylic acid in which the hydrogen atom of the hydroxyl group has been replaced by an alkyl group. The general structure is the product of the union of the function of carboxylic acid (the R group) and the carbon chain that forms the alcohol (the R' group) .

How do you name a carboxylic ester?

Naming the esters is very easy, they are named after the carboxylic acid from which they come; the names of carboxylic esters include prefixes that denote the lengths of the carbon chains in the molecules and are derived following rules of nomenclature similar to those of inorganic acids and salts, for example:
