Which one is the common name of the compound CH2=CH-CHO?
A
Mesityl Oxide
B
Prop-2-Enal
C
Acrolein
D
Propanal-1-ene
Answer
Acrolein
Explanation
Solution
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.
