Esters and Carboxylic acid

Carboxylic acid

They occur widely in nature, often combined with alcohols or other functional groups, as in fats, oils, and waxes.

Carboxylic acid

They are components of many foods, medicines, and household products.

Carboxylic acidd

Not surprisingly, many of them are best known by common names based on Latin and Greek words that describe their source.

Formic acid

Acetic acid

Propionic acid

Butyric acid

These carboxylic acid devicatives (?) are miscible in water
