Esters: physical properties
- Esters are polar but have no O–H group, so their molecules cannot hydrogen-bond to each other and they boil lower than alcohols and carboxylic acids of similar size.
- Small esters dissolve somewhat in water because they can accept hydrogen bonds.
- Many esters have pleasant fruity smells and are used in flavours and perfumes.
- An ester boils well below a carboxylic acid of similar size, because the acid's O–H lets its molecules hydrogen-bond to each other.
