Question

Green chemistry means such reactions:
(a)- produce color during reactions
(b)- reduce the use and production of hazardous chemicals.
(c)- are related to the depletion of the ozone layer
(d)- study the reactions in plants

Answer 1

Hint: Green chemistry is related to the effects of the polluting chemicals on plants and animals. It is used for making the environment safer for living things. It is also called sustainable chemistry.

Complete answer:
The green chemistry which is also known as sustainable chemistry is the branch of the branch which deals with the design of products and processing it so that it minimizes or eliminates the use and generation of hazardous substances.
It is different from environmental chemistry because environmental chemistry is based on the study of the effects of pollution-causing chemicals, whereas green chemistry is based on the environmental impact of chemistry. It mainly focuses on preventing pollution by reducing the consumption of non-renewable resources.
The goals of green chemistry are producing more efficient products, producing safer molecules, and can be used in a variety of fields. It only uses renewable materials.

There are some principles of green chemistry:
-Prevention of waste.
-Synthesis of chemicals which are less hazardous.
-Products are designed for energy efficiency.
-Using a catalyst, which would increase the rate of the reaction.
-Renewable feedstock, renewable sources are preferably over the non-renewable sources.

So, the correct answer is “Option B”.

Note: Don't get confused between environmental chemistry and green chemistry, they both have different aspects. The solvents used in green chemistry are green solvents. They are less harmful to humans and the environment.
