Question

CH3CH2COOH reacts with cl2 and red Phosphorus gives

Answer 1

Explanation:

alpha chloro propanoic acid

Answer 2

When propionic acid reacts with chlorine in the presence of red phosphorous , 2-chloropropionic acid is formed .

      CH$_{3}$CH$_{2}$COOH + Cl$_{2}$ / red P  →  CH$_{3}$CH(Cl)COOH

• 2-Chloropropionic acid ( CH$_{3}$CH(Cl)COOH ) is used to prepare propargyl 2-chloropropionate (PCP) which is used as an atom transfer radical polymerization (ATRP) initiator .

• Propionic acid is used as a flavoring agent and preservative .
