A) Hunsdiecker reaction
B) Vilsmeier reaction
C) Finkelstein reaction
D) Hell-Volhard-Zelinsky reaction
Correct Answer: D
Solution :
In Hell-Volhard-Zelinsky reaction, a-hydrogen of a carboxylic acid can be replaced by halogen using red phosphorus. \[R-C{{H}_{2}}COOH+{{X}_{2}}\xrightarrow{\operatorname{Re}d\,P}R-\underset{\begin{smallmatrix} | \\ X \end{smallmatrix}}{\mathop{C}}\,H-COOH\]\[\alpha \]-halogenated acids are in fact good starting material for preparing other a-substituted acids.You need to login to perform this action.
