The correct answer is option (C): Acrolein
1.The common name of CH₂=CH-CHO is acrolein. Acrolein is an unsaturated aldehyde and its chemical formula is C₃H₄O. It has a pungent odor and is colorless to yellowish in color. 2. The chemical formula for mesityl oxide is (CH₃)₂C=CHC(O)CH₃. It is a colorless organic compound with a pleasant peppermint-like odor. 3. Prop-2-enal has a chemical formula C₃H4O. It is an unsaturated aliphatic compound with an aldehyde group. The IUPAC name is prop-2-enal. 4. Propanal-1-ene is not a valid chemical name for an IUPAC name. So, the correct answer is Acrolein.
