Maximum decarboxylation occurs in

Question

Maximum decarboxylation occurs in (A) CH3COOH (B) C6H5COOH (C) C6H5CH2COOH (D) CH3COCH2COOH

Tardigrade Admin · Accepted Answer

CH3COCH2COOH is a β-keto acid. Thus decarboxylation is maximum in a carboxylic acid containing an electron withdrawing group such as >CO or - COOH at the β-carbon atom with respect to the - COOH group.

Q. Maximum decarboxylation occurs in

$C H_{3} COO H$

$C_{6} H_{5} COO H$

$C_{6} H_{5} C H_{2} COO H$

$C H_{3} COC H_{2} COO H$

$C H_{3} COC H_{2} COO H$ is a $β$ -keto acid. Thus decarboxylation is maximum in a carboxylic acid containing an electron withdrawing group such as $> CO$ or $- COO H$ at the $β$ -carbon atom with respect to the $- COO H$ group.

Q. Maximum decarboxylation occurs in

CH3​COOH

C6​H5​COOH

C6​H5​CH2​COOH

CH3​COCH2​COOH

CH3​COCH2​COOH is a β-keto acid. Thus decarboxylation is maximum in a carboxylic acid containing an electron withdrawing group such as >CO or −COOH at the β-carbon atom with respect to the −COOH group.

$C H_{3} COO H$

$C_{6} H_{5} COO H$

$C_{6} H_{5} C H_{2} COO H$

$C H_{3} COC H_{2} COO H$

$C H_{3} COC H_{2} COO H$ is a $β$ -keto acid. Thus decarboxylation is maximum in a carboxylic acid containing an electron withdrawing group such as $> CO$ or $- COO H$ at the $β$ -carbon atom with respect to the $- COO H$ group.
