Question

Define green chemistry. What are its objectives?

Answer 1

Hint: We know that green chemistry can be stated as the structure or design of chemical products and processes which reduces or completely eliminates the usage or generation of dangerous substances. Green chemistry is applied across the whole life cycle of a chemical product, including the designing, manufacturing, usage, and its ultimate disposal.

Complete answer:
As we know , green chemistry is also called sustainable chemistry. There are twelve principles of green chemistry; chemical products should be designed in order to achieve the expected or desired function while being most non-toxic, they can be. Safer solvents and auxiliaries. Auxiliary substances should not be used wherever there is no need, and also as non-hazardous as it could be when they must be used. Green chemistry is also known as sustainable chemistry, it is a part of chemistry and chemical engineering which is focused on the design and structure of products and processes that reduces or eliminates the usage and generation of hazardous or dangerous substances.
Green chemistry arises from a variety of existing ideas and efforts of research such as atom economy and catalysis in the time leading. Green chemicals either degrade to harmless products or are recovered for future use. Plants and animals also suffer very less harm from toxic chemicals which are present in the environment. Lower the potential for global warming, ozone depletion, and smog formation. Also, less chemical disturbance of ecosystems. The objectives are as follows as:
1.Prevents pollution at the molecular level.
2.Is a philosophy that applies to all areas of chemistry, not a single discipline of chemistry.
3.Applies innovative scientific solutions to real-world environmental problems.
4.Results in source reduction because it prevents the generation of pollution.
5.Reduces the negative impacts of chemical products and processes on human health and the environment.

Note:
Remember that the energy requirements would be recognized for their environmental and economic impacts should be minimized. Energy is required for any organic reaction in the form of heat, light, etc. Most of the energy is obtained from fossil fuels such as coal, petroleum, etc. Which have a major environmental effect. It is now possible to carry out reactions by using microwaves, ultrasound which is advantageous and non-polluting.
