Question

An organic acid $\left(A\right)$ reacts with concentrated $H_{2}S{O}_4$ to give neutral oxides $\left(B\right)$, amphoteric oxide $\left(C\right)$ and an acidic oxide $\left(D\right).$ Choose the correct option(s):

• A. The compound $\left(A\right)$ is $H_2{C}_2{O}_4$
• B. The compound $\left(A\right)$ is $CHC{l}_3$
• C. The acidic oxide $\left(D\right)$ is $C{O}_2$
• D. The acidic oxide $\left(D\right)$ is $CO$

Answer 1

Answer: (A), (C)

The acidic oxide $\left(D\right)$ is $C{O}_2$

Conc. $H_{2}S{O}_4$ is a strong dehydrating agent. It removes water from organic compounds.
$\underset{\left(A\right)}{(COOH{)}_2}\stackrel{conc.H_{2}S{O}_4}{\to }\underset{\left(B\right)}{CO}+\underset{\left(D\right)}{C{O}_2}+\underset{\left(C\right)}{H_{2}O}$
