Question

In Hunsdiecker reaction

• A. number of carbon atoms decrease
• B. number of carbon atoms increase
• C. number of carbon atoms remain same
• D. carboxylic acid is formed

Answer 1

The correct option is A number of carbon atoms decrease

$RCCOAg+B{r}_2\to R-Br+C{O}_2+AgBr$

Hunsdiecker reaction is defined as the reaction that involves the reacting of carboxylic acids silver salts with halogens to form an unstable intermediate that further undergoes decarboxylation thermally leading to final product that is alkyl halide with the evolution of carbon dioxide
