In an experimental setup, a chemist synthesizes a unique organic compound "E" with a molecular formula $\mathrm{C}_{7} \mathrm{H}_{6} \mathrm{O}_{4}$. When " $E$ " is treated with hydrazine $\left(\mathrm{N}_{2} \mathrm{H}_{4}\right)$, it yields a compound " $F$ " $\left(\mathrm{C}_{7} \mathrm{H}_{8} \mathrm{~N}_{2} \mathrm{O}_{2}\right)$. Further, on heating compound " $F$ " with a mild oxidizing agent, it forms a compound "G" $\left(\mathrm{C}_{7} \mathrm{H}_{6} \mathrm{~N}_{2} \mathrm{O}_{4}\right)$. Analyze these transformations and determine the likely structures of compounds $E, F$, and $G$. Also, explain the type of chemical reactions involved in each step.

Accepted Answer

∻Solution∻ ‖ 1 ⋮ **Identify the molecular formula and initial reaction**: The molecular formula of compound "E" is $C_7H_6O_4$. When treated with hydrazine ($N_2H_4$), it forms compound "F" with the molecular formula $C_7H_8N_2O_2$. This suggests a reduction reaction where hydrazine reduces the compound. ‖ ‖ 2 ⋮ **Analyze the structure of compound "E"**: Given the molecular formula $C_7H_6O_4$, compound "E" could be a benzene derivative with carboxyl and hydroxyl groups. A plausible structure is 2,3-dihydroxybenzoic acid. ‖ ‖ 3 ⋮ **Determine the structure of compound "F"**: The molecular formula $C_7H_8N_2O_2$ indicates that two oxygen atoms are replaced by nitrogen atoms from hydrazine. This suggests the formation of a hydrazone derivative. A likely structure is 2,3-dihydroxybenzohydrazide. ‖ ‖ 4 ⋮ **Analyze the oxidation reaction to form compound "G"**: Heating compound "F" with a mild oxidizing agent forms compound "G" with the molecular formula $C_7H_6N_2O_4$. This suggests the introduction of additional oxygen atoms, likely forming a dihydroxybenzohydrazone. ‖ ∻Answer∻ ⚹ Compound "E" is 2,3-dihydroxybenzoic acid, compound "F" is 2,3-dihydroxybenzohydrazide, and compound "G" is 2,3-dihydroxybenzohydrazone. ⚹ ∻Key Concept∻ ⚹ Organic synthesis and functional group transformations ⚹ ∻Explanation∻ ⚹ The transformations involve reduction by hydrazine and subsequent oxidation, leading to changes in functional groups while maintaining the benzene ring structure. ⚹◊What is the balanced chemical equation for the reaction between compound "E" and hydrazine⍭ Generate me a similar question◊
