Objective: to know the use of carboxylic acids in our life, chemical structure, physical properties and nomenclature

Results:
1-. Define Carboxylic acids.

The carboxyc acids are alkyl andaromatic groups united to a carboxylic group.

2-. Describe the characteristic that differentiates them from other organic compounds.

Some characteristics of carboxylic acids to an alcohol,aldehyde and a ketone are:
• They contain two oxygens
• Its carbonyl group is at primary carbon
• if a carboxylic acid has more than 5 carbons, they are not soluble in water.


3-.Search the physical properties (solubility, fusion point and melting point) of at least 15 carboxylic acids and write them in a table.
