What is IUPAC name of acrylic acid?
What is IUPAC name of acrylic acid?
Options
- A3-Methylbut-3-enoic acid
- B3-Methylpent-2-enoic acid
- CProp-2-enoic acid
- DBut-3-enoic acid
Correct answer
C. Prop-2-enoic acid
Step-by-step solution
The chemical formula of acrylic acid is .
The principal functional group is the carboxylic acid group (), so numbering starts from the carboxyl carbon.
The longest carbon chain contains carbon atoms, giving the root word 'prop'.
A double bond is present between and , which is indicated by '2-en'.
The secondary suffix for the carboxylic acid is 'oic acid'.
Combining these parts, the IUPAC name is Prop-2-enoic acid.
