MHT CET 2022 Chemistry question

Not in JEE or NEET syllabus

Which among the following statements is NOT true according to principles of green chemistry?

(A)Use of catalyst minimize waste.
(B)Benzene being volatile compound pollutes air.
(C)Carrying out reactions at high temperature and high pressure minimizes use of energy.Correct
(D)Use renewal chemicals rather than crude oil.

Answer: (C)

Solution

Green chemistry principles aim at waste prevention, safer solvents, energy efficiency, renewable feedstocks and catalysis. (a) is true: catalytic reagents are selective and used in small amounts, so less waste is generated. (b) is true: benzene is a volatile, toxic solvent that pollutes air, so safer solvents are
