Question:
Acetaldehyde, when heated in the presence of sodium hydroxide and iodine forms
Acetaldehyde, when heated in the presence of sodium hydroxide and iodine forms
Show Hint
This is the iodoform reaction: CH$_3$CHO gives CHI$_3$ and sodium formate.
Updated On: Oct 1, 2026
- Sodium formate
- Sodium acetate
- Ethanol
- Iodoethane
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Recognise the test
Compounds with a CH\(_3\)CO- group give the iodoform reaction with I\(_2\) and NaOH.
Step 2: Write the reaction
\[ \text{CH}_3\text{CHO}+3\text{I}_2+4\text{NaOH}\to\text{CHI}_3+\text{HCOONa}+3\text{NaI}+3\text{H}_2\text{O} \]
Step 3: Result
The salt formed is sodium formate. Option (A).
Final Answer:
The product salt is sodium formate, option (A). \[ \boxed{\text{(A)}} \]
