What is the product when acetylene reacts with hypochlorous acid ?

1. CH3COCl
2. ClCH2CHO
3. Cl2CHCHO
4. ClCHCOOH

Correct answer: Cl2CHCHO

Solution

The reaction between acetylene and hypochlorous acid leads to the formation of a compound where chlorine atoms are added to the carbon chain, resulting in the product Cl2CHCHO, which contains both the aldehyde functional group and two chlorine substituents.
