Which of the following practices will not come under green chemistry?
1 If possible, making use of soap made of vegetable oils instead of using synthetic detergents.
2 Using \(\mathrm{H}_{2} \mathrm{O}_{2}\) for bleaching purpose instead of using chlorine based bleaching agents.

Green chemistry means such reactions which:
1 produce colour during reactions
2 reduce the use and production of hazardous chemicals
3 are related to the depletion of ozone layer
4 study the reactions in plants
Explanation:
Greenchemistry may be defined as the programme of developing new chemical products and chemical processes or making improvements in the already existing compounds and processes so as to make less harmful to human health and environment. This means the same as to reduce the use and production of hazardous chemicals. i.e., correct answer is option (2)

By green chemistry we mean
1 Producing chemicals of our daily use from greenhouse gases
2 Performing chemical processes which use green plants
3 Performing only those reactions which are of biological origin
4 The use of non-toxic reagents and solvents to produce environmental friendly products.
