Carboxylic acids having at least one `alpha`-hydrogen react with `Cl_(2)" or "Br_(2)` in the presnence of red phosphorus to give `alpha`-halo acids. The reaction is known as H.V.Z. reaction. The HVZ reaction is limited to the formation of `alpha`-chloro acid and `alpha`-bromo acid and it is sometimes difficult to carry out the reaction. Answer the following questions :
Which of the following carboxylic acids will not give HVZ reaction ?

Carboxylic acids having at least one alpha -hydrogen react with Cl_(2) or Br_(2) in the presence of phosphorous to give alpha -halo acids. The reaction is known as Hell -volhar-Zelinsky reaction (HVZ reaction). R-CH_(2)-CO OH overset(P//Br_(2))underset(Delta)toR-CH(Br)CO OH The HVZ reaction is limited to the formation of alpha -chloro and alpha -bromo acids and it is sometimes backward to carry out. the reagents ( X_(2) and P ) are noxious and the reaction time is often long and the conditions of reaction are harsh. Which of the following carboxylic acids will not give HVZ reaction ?
