Step-by-step solution

Understanding the Question

The question asks about the use of benzene hexachloride. It's a multiple-choice question with four options: dye, insecticide, antimalarial drug, and antibiotic.

Identifying Benzene Hexachloride

Benzene hexachloride is also known as BHC or Lindane. It is a chemical compound that has several industrial and agricultural applications.

Recognizing its Applications

One of the primary uses of benzene hexachloride is as an agricultural chemical. It is widely known for its use as an insecticide, mainly for killing pests.

Concluding the Solution

Given the options, the correct answer aligns with the known use of benzene hexachloride as an insecticide. Therefore, option (b) is the correct choice.

Key concepts

Insecticide

Benzene hexachloride, often referred to as BHC or Lindane, is highly recognized as an effective insecticide. As an insecticide, it works by targeting the nervous system of insects, disrupting their neurological functions which ultimately leads to their death. This property makes it very useful in controlling unwanted insect populations in various settings.

Insecticides like benzene hexachloride are vital in maintaining ecological balance by keeping pest populations in check. This, in turn, prevents the spread of plant diseases and increases agricultural productivity. In household settings, BHC helps in managing pests, ensuring a cleaner and safer living environment.

It is important to note that due to its potency, careful handling and regulated use are essential when dealing with such chemicals to minimize any negative impact on non-target species, including humans.

Chemical Compounds

Benzene hexachloride is a chemical compound characterized by its inclusion of benzene as a structural component. The chemical formula for BHC is \( C_6H_6Cl_6 \). This indicates the presence of six chlorine atoms bonded to a benzene ring, altering both its physical and chemical properties significantly from its parent molecule.

The unique properties of benzene hexachloride make it suitable for various applications. Its chemical structure provides the stability and reactivity needed to function effectively as an insecticide.

Understanding the chemistry of compounds like benzene hexachloride is essential for safely harnessing their benefits. The study of these compounds involves examining how they interact with biological systems and other chemicals in the environment, thereby guiding safe usage and regulatory measures.

Agricultural Applications

In the realm of agriculture, benzene hexachloride plays a crucial role in pest management. Farmers utilize it to protect crops from insect infestations that can lead to significant yield losses. By applying BHC, they ensure that food production is more reliable and abundant, addressing global food supply challenges.

Beyond crop protection, benzene hexachloride is applied to control pest populations that affect livestock. Effective pest management in the agricultural industry not only preserves the quality of the produce but also helps in maintaining the overall health of farm animals, which can be adversely affected by insects such as ticks and lice.

Despite its benefits, the use of BHC in agriculture must be carefully managed. It's vital to follow guidelines and regulations to avoid contaminating the environment and to prevent the development of insecticide-resistant pests. Proper training in the usage of such chemicals is imperative for anyone involved in their application.
