Which of the following represents the reaction of ethene with hypochlorous acid to form a product neutralized by sodium bicarbonate?

1. CH₂=CH₂ + HOCl → CH₂OH + NaHCO₃
2. CH₂OH
3. CH₂Cl
4. CH₂OH

Correct answer: CH₂=CH₂ + HOCl → CH₂OH + NaHCO₃

Solution

The reaction of ethene (CH₂=CH₂) with HOCl results in the formation of CH₂Cl-CH₂OH, as HOCl adds across the double bond. This is a standard electrophilic addition reaction.
