Determine whether each phrase describes carboxylic acids or esters. Usually have a sour odor.
Form hydrogen bonds amongst themselves and have lower vapor pressure.
Do not form hydrogen bonds amongst themselves and have higher vapor pressure.
Notable for their pleasant fragrances.
Their reactions with base are known as saponifications.
Their reactions with base are known as neutralizations.

Carboxylic acids produce hydrogen bonds amongst themselves and possess lower vapor pressure. They generally possess a sour odor. When an acid and a base react with each other to produce salt and water and comprises the combination of hydrogen and hydroxide ions, the reaction is termed the neutralization reaction. Thus, when carboxylic acid reacts with base the reaction is termed neutralization.

On the other hand, esters are known for their pleasant fragrances. They do not produce hydrogen bonds amongst themselves and possess higher vapor pressure. A hydration reaction in which free hydroxide dissociates the ester bonds between the glycerol and fatty acids of a triglyceride, leading to the formation of free fatty acids and glycerol is termed saponification.

Thus, the given blanks can be filled with carboxylic acid, carboxylic acid, esters, esters, esters, and carboxylic acid.

i just learnt this recently but i need to look through my notes again

thats how its supposed to be
