(A) Pure $CHCl_3$ (chloroform) and $CHI_3$ (iodoform) are both haloforms. $CHCl_3$ is a liquid at room temperature,while $CHI_3$ is a yellow solid. However,chemically,they can be distinguished by their reaction with aqueous $AgNO_3$. $CHCl_3$ does not give a precipitate with aqueous $AgNO_3$ because the $C-Cl$ bond is covalent and does not ionize to release $Cl^-$ ions. Similarly,$CHI_3$ does not give a precipitate with aqueous $AgNO_3$. Actually,the most common way to distinguish them is by their physical state or by heating with aqueous $KOH$ followed by testing the resulting halide ions. However,among the given options,the reaction with aqueous $AgNO_3$ is often cited in textbooks to show that neither forms a precipitate,but they can be distinguished by their physical appearance (liquid vs solid). Given the standard chemistry curriculum,$CHI_3$ is a yellow solid with a characteristic smell,while $CHCl_3$ is a colorless liquid. If we must choose a reagent,none of the options provided directly distinguish them via a simple precipitate test as both are stable. However,in many competitive exams,this question is framed to test the knowledge of physical properties or specific chemical tests. Based on standard practice,the physical state is the primary differentiator.
