Question:

$\text{The practice that does not come under green chemistry among the following is-}$

Options:

1. $\text{Making use of soap made of vegetable oils instead of using synthetic detergents.}$
2. $\text{Using } \text{H}_2\text{O}_2 \text{ for bleaching purposes instead of using chlorine-based bleaching agents.}$
3. $\text{Using bicycles for traveling small distances instead of using petrol/diesel based vehicles.}$
4. $\text{Using plastic cans for neatly storing substances.}$

Solution:

$\text{HINT: Plastic materials are non-biodegradable}$ $\text{Explanation:}$ $\text{STEP 1: Green chemistry, also called sustainable chemistry, is an area of chemistry and chemical engineering focused on the design of products and processes that minimize or eliminate the use and generation of hazardous substances.}$ $\text{STEP 2: Using plastic cans for neatly storing substances will not under green chemistry. Water in lakes and rivers have been polluted by the use of plastic materials. The plastic materials are non-biodegradable.}$ $\text{All other methods come in green chemistry.}$
