Question

Acrolein is a hard,horny and a high melting point material. Which of the following represent its structure:

• A.
• B.
• C.
• D.

Answer 1

The Correct Option is A

To determine the correct structure of acrolein, let's first understand what acrolein is. Acrolein (systematic name: propenal) is an organic compound with the formula CH₂=CHCHO. It is a colorless or yellow liquid with a pungent odor and is a member of the aldehyde group of compounds. In the context of the question, acrolein is not a hard, horny, or high melting point material; this description might be an error or misinterpretation.

Now, let's evaluate the options provided for the structure of acrolein. The correct structural representation typically involves the following features:

• A three-carbon backbone with a carbon-carbon double bond on one end and an aldehyde group (CHO) on the other.
• The structural formula is CH₂=CH-CH=O, showing the aldehyde group attached to the terminal carbon of the double bond.

Given these characteristics, let's identify the correct structure from the options available:

The structure shown above matches the typical formula and arrangement of acrolein (propenal), where you see a carbon-carbon double bond (CH₂=CH-) followed by an aldehyde group (CHO).

Thus, the structure provided in this option correctly represents acrolein:

Answer: The correct structure of acrolein is represented by the first option shown in the image above.
