Identify \('X'\) along with oxidation state of halogen in the given reaction: \(3Cl_2 + 6NaOH \longrightarrow 5NaCl + X + 3H_2O\) (hot and conc.) |
\(NaClO_2\), +3 \(NaClO_3\), +5 \(NaClO_2\), +7 \(NaClO_3\), +1 |
\(NaClO_3\), +5 |
The correct answer is option 2. \(NaClO_3\), +5. Let us break down the explanation step by step: 1. Understanding the Reaction: The given reaction is a disproportionation reaction of chlorine (\(Cl_2\)) in the presence of hot and concentrated sodium hydroxide (\(NaOH\)): \[ 3Cl_2 + 6NaOH \longrightarrow 5NaCl + X + 3H_2O \] 2. Identification of \(X\): In the reaction, chlorine (\(Cl_2\)) is both oxidized and reduced simultaneously. It is oxidized to form a compound represented by \(X\) and reduced to form sodium chloride (\(NaCl\)). We need to identify \(X\) and determine its composition. 3. Possible Chlorine Compounds: Chlorine can exhibit various oxidation states, including -1, +1, +3, +5, and +7. To find \(X\), we need to consider compounds where chlorine has a positive oxidation state. 4. Oxidation States of Chlorine: \(NaClO_2\): In this compound, chlorine has an oxidation state of +3. \(NaClO_3\): In this compound, chlorine has an oxidation state of +5. \(NaClO_2\): In this compound, chlorine has an oxidation state of +7. \(NaClO_3\): In this compound, chlorine has an oxidation state of +1. Since the given reaction involves the formation of a compound (\(X\)) where chlorine is oxidized, and the options provide compounds with different oxidation states of chlorine, we need to choose the compound where chlorine has an oxidation state of +5. This corresponds to option (2) \(NaClO_3\). Therefore, \(X\) in the reaction is \(NaClO_3\), and the oxidation state of chlorine in \(NaClO_3\) is +5. This compound is formed during the disproportionation of chlorine in hot and concentrated sodium hydroxide solution. |
