Greetings,
At this beautiful time of the year in the northern hemisphere, when fragrant flowers and fruits are in full bloom, I am reminded of the delightful aroma of Esters. The Ester is yet another class of organic compound with its own special properties. Esters are compounds which provide many refreshing aromas and flavors; many of which have a very recognizable odor of a type of fruit. One example is Ethyl Acetate, which smells like bananas.
The Ester functional group very much resembles that of the carboxylic acids, but the acidic hydrogen is replaced with an alkyl group, such as the methyl group. The graphic below shows the general Lewis Structure of the Ester class of Compounds, with a specific example included.
Two different "R" groups are indicated with the general Lewis structure to emphasize two separate alkyl groups. The Ball-and-Stick model shown on the right side is, literally, a combination of a methyl group and an Acetate group, hence the name.
The Ester type of compound was actually part of a prior post which included an example of Biodiesel fuel
That's all for now. As always, thank you for reading!
