Question

The structures below represent propanol (propyl alcohol) and benzoic acid. Circle on each structure the part of each molecule that is the "functional group," that is the atoms that are characteristic of alcohol (propanol) and carboxylic acids (benzoic acid) Write the molecular formula (i.e. C_xH_yO_z) of each molecule Propanol: Benzoic Acid: Determine the mass of one mole (formula mass) of each substance, expressed in 8/mol Propanol: Benzoic Acid: Sketch the structural formula of the ester formed when propanol and benzoic acid react. This ester, called "propyl benzoate," is present in sweet cherries and clove stems. It has a nutty odor and taste and is used as a food additive

Explanation / Answer

Dear Student,

The answers to the above mention questions are as follows :

a. The encircled molecule in the diagram is the -OH group which represents alcohol. When propane is reacted with alcohol the final product is propanol.

The encircled molecule in the diagram is the COOH group which represents carboxylic acid. When benzene is reacted with carboxylic acid the final product is benzolic acid.

b. Molecular Formula for Propanol is C3H8O

Molecular Formula for Benzoic Acid is C7H6O2

c. Formula Mass of Propanol is 60.10 g/mol

Formula Mass of Benzoic Acid is 122.12 g/mol

d. When propanol is reacted with benzoic acid the final product is the ester " propyl benzoate"

Structural Formula of Propyl Benzoate is
