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 CH₂=CH-COOH . The principal functional group is the carboxylic acid group ( -COOH ), so numbering starts from the carboxyl carbon. The longest carbon chain contains 3 carbon atoms, giving the root word 'prop'. A double bond is present between C₂ and C₃ , 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. Answer: Prop-2-enoic acid
