Q. Which of the following does not give HVZ reaction?
A) $CH_{3}CH_{2}COOH$
B) $CH_{3}COOH$
C) $HCOOH$
D) $\left( CH_{3} \right)_{2}CHOH$
Explanation
(c)
In Hell-Volhard Zelinsky reaction, when acid reacts with $Br_{2}$ or $Cl_{2}$ in presence of red phosphorus $\alpha$-hydrogen atom of the acid is replaced by halogen atom. HCOOH does not give HVZ reaction due to absence of $\alpha$-hydrogen atom
