Difficulty: HardChemistry in Daily Life and Industrial Applications

Match the chemical substances listed in List I with their corresponding primary industrial applications or daily life functions in List II.

  • ChloroxylenolActive antiseptic agent in commercial disinfectant liquid formulations
  • Melamine-Formaldehyde ResinThermosetting polymer utilized in manufacturing shatterproof dinnerware
  • Bordeaux MixtureInorganic fungicide and bactericide applied in agricultural crop protection
  • Potassium NitrateOxidizing component used in gunpowder and pyrotechnic formulations

Answer

Chloroxylenol matches with active antiseptic agent in commercial disinfectant liquid formulations; Melamine-Formaldehyde Resin matches with thermosetting polymer utilized in manufacturing shatterproof dinnerware; Bordeaux Mixture matches with inorganic fungicide and bactericide applied in agricultural crop protection; and Potassium Nitrate matches with oxidizing component used in gunpowder and pyrotechnic formulations.
Chloroxylenol functions as an active antiseptic in disinfectant liquids; Melamine-Formaldehyde Resin is a thermosetting plastic used for durable dinnerware; Bordeaux Mixture is a copper-based agricultural fungicide; and Potassium Nitrate serves as an oxidizing agent in propellant and pyrotechnic mixtures.

Step-by-Step Solution

1
Analyze the chemical nature and application of Chloroxylenol.
Chloroxylenol (C8H9ClOC_8H_9ClO) is a halogenated phenolic antiseptic.
It disrupts microbial cell membranes and inactivates key cellular enzymes, making it the active ingredient in antimicrobial products.
2
Evaluate the structure and utility of Melamine-Formaldehyde Resin.
It is formed via condensation polymerization of melamine with formaldehyde.
Extensive three-dimensional cross-linking renders it rigid, durable, and heat-resistant, ideal for shatterproof kitchenware.
3
Examine the composition and agricultural role of Bordeaux Mixture.
It is prepared by combining copper sulfate (CuSO4CuSO_4) solution with slaked lime (Ca(OH)2Ca(OH)_2) suspension.
The released copper ions (Cu2+Cu^{2+}) inhibit fungal spore germination on crops such as grapes and potatoes.
4
Identify the industrial function of Potassium Nitrate.
Potassium nitrate (KNO3KNO_3) readily undergoes thermal decomposition to liberate oxygen gas.
This rapid oxygen supply drives the rapid oxidation of fuels (sulfur and charcoal) in gunpowder and pyrotechnic compositions.
