Ethers are relatively inert and make good organic solvents. Aldehydes and ketones have a carbon oxygen double bond. If the double bond is at the end of a chain the molecule is called an aldehyde. If the double bond occurs away from an end the compound is called a ketone. Organic Acids have a COOH group with a weakly held hydrogen atom that can be ionized in water.
Most organic acids are very weak.
A neutralization reaction occurs and leaves the organic equivalent of a salt. Esters usually have a pleasant fruit-like flavor. Carbohydrates are compounds of carbon, hydrogen, and oxygen that have two atoms of hydrogen for each atom of oxygen. Two simple sugars are often linked to form a disaccharide . Polysaccharides are complex sugars consisting of chains of the simple sugars.
