Question

What is the common name of $C{{H}_{2}}=CHCOOH$ ?
A. Anthranilic acid
B. Citric acid
C. Acrylic acid
D. Propenoic acid

Answer 1

Common name is nothing but a nomenclature system used to write the names of the simple organic molecules. Writing a common name for complex molecules is impossible. So, to write the names of complex organic molecules we use IUPAC nomenclature.

Complete step by step answer:
- The given compound in the question is $C{{H}_{2}}=CHCOOH$ .
- The given compound contains two functional groups. One is alkene and the other is carboxylic acid.
- The given compound contains three carbons, four hydrogens and two oxygen atoms.
- The structure of the given molecule resembles the structures of the acrolein.
- The structure of the acrolein is as follows.

- The structure of the given molecule is as follows.

- Therefore the common name of the given compound is acrylic acid.

- So, the correct option is C.

Additional information:
- IUPAC name of Acrylic acid is propenoic acid.
- Acrylic acid is an organic compound.
- Acrylic acid is the simplest unsaturated carboxylic acid containing a vinyl group associated directly to a carboxylic acid functional group.
- Acrylic acid is a colorless liquid.
- Acrylic acid is miscible with water and alcohol.
- The word acrylic acid is coined in 1843 because it is a derivative of acrolein.

Note: Acrylic acid can be prepared from the propylene by oxidation.
The chemical reaction of preparation of acrylic acid from propylene is as follows.
