Which hydrogen atom of acetic acid is replaced by `Cl_(2)` in presence of red P ?

Options

A. `alpha`-hydrogen
B. carboxylic hydrogen
C. both 1 and 2
D. oxygen of carboxylic group

Answer

1

Explanation

`CH_(3)CO OH overset(Red p)underset(Cl_(2))tounderset("monochloro acetic acid ")(CH_(2)ClCO OH overset(Red P)underset(Cl_(2))tounderset("di-chloro acetic acid")(CHCl_(2)CO OH) CO OH)`
`CH_(2)CO CH_(2)Cl_2 CO OH overset(redP)(underset(Cl_(2))underset("tri-chloro acetic acid")(Cl_(3)C CO OH)`
In the above reaction `alpha` hydrogens are replaced by chlorine
