Question

The chemical reaction, R-CH2COOH xrightarrow[(ii) H2O](i) X2/ textred phosphorus R- underset overset|XCH-COOH is known as (A) Hunsdiecker reaction (B) Vilsmeier reaction (C) Finkelstein reaction (D) Hell-Volhard-Zelinsky reaction

Tardigrade Admin · Accepted Answer

In Hell-Volhard-Zelinsky reaction, a-hydrogen of a carboxylic acid can be replaced by halogen using red phosphorus.

R - C H_{2} COO H + X_{2} Red P R - X ∣ C H - COO H

α

-halogenated acids are in fact good starting material for preparing other a-substituted acids.

Q. The chemical reaction, R−CH2​COOH(i)X2​/red phosphorus(ii)H2​O​R−X∣C​H−COOH is known as

Hunsdiecker reaction

Vilsmeier reaction

Finkelstein reaction

Hell-Volhard-Zelinsky reaction

In Hell-Volhard-Zelinsky reaction, a-hydrogen of a carboxylic acid can be replaced by halogen using red phosphorus. R−CH2​COOH+X2​Red P​R−X∣C​H−COOH α -halogenated acids are in fact good starting material for preparing other a-substituted acids.

Q. The chemical reaction,
$R - C H_{2} COO H (i) X_{2} / red phosphorus (ii) H_{2} O R - X ∣ C H - COO H$ is known as

In Hell-Volhard-Zelinsky reaction, a-hydrogen of a carboxylic acid can be replaced by halogen using red phosphorus.
$R - C H_{2} COO H + X_{2} Red P R - X ∣ C H - COO H$
$α$ -halogenated acids are in fact good starting material for preparing other a-substituted acids.
