Question:
Match the following
Methyl chloride - Antiseptic
Chloroform - Metal washing
Iodoform - Propellant
\( \text{CCl}_4 \) - Solvent for \( \text{I}_2 \)
Match the following
Methyl chloride - Antiseptic
Chloroform - Metal washing
Iodoform - Propellant
\( \text{CCl}_4 \) - Solvent for \( \text{I}_2 \)
Methyl chloride - Antiseptic
Chloroform - Metal washing
Iodoform - Propellant
\( \text{CCl}_4 \) - Solvent for \( \text{I}_2 \)
Show Hint
Uses of haloalkanes are common memory-based questions. Always link Iodoform to 'antiseptic' (iodine release), Freons/Methyl chloride to 'refrigerant/propellant', and heavy liquids like $\text{CCl}_4$/Chloroform to 'solvents/degreasers'.

Solution and Explanation
Step 1: Understanding the Concept:
This question tests factual knowledge regarding the commercial and industrial applications of common polyhalogen compounds.
Step 2: Key Formula or Approach:
Recall the specific uses listed in standard chemistry curricula (like NCERT) for each given compound to form correct pairs.
Step 3: Detailed Explanation:
Let's analyze the properties and uses of each compound:
1. Methyl chloride (\(\text{CH}_3\text{Cl}\)): It is used as a propellant.
2. Iodoform (\(\text{CHI}_3\)): It is used as an antiseptic.
3. Carbon tetrachloride (\(\text{CCl}_4\)): Used for metal washing (degreasing).
4. Chloroform (\(\text{CHCl}_3\)): Used as a solvent for iodine.
Matching:
Methyl chloride → Propellant
Iodoform → Antiseptic
CCl₄ → Metal washing
Chloroform → Solvent for I₂
Step 4: Final Answer:
Methyl chloride - Propellant; Chloroform - Solvent for I₂; Iodoform - Antiseptic; Carbon tetrachloride - Metal washing.
