2-Methylpropanal
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
Glyoxal has the formula \(\text{OHC-CHO}\).
Step 2: Naming
Two carbons give the parent name ethane, and two -CHO groups give the suffix dial.
Final Answer:
The IUPAC name of glyoxal is ethanedial. \[ \boxed{\text{(A) }\text{Ethanedial}} \]
