Question
In what ways does this Diels-Alder reaction better exhibit the principles of Green Chemistry than the Grignard experiment?
a. The Diels-Alder is solvent-less, and the Grignard required ether as the solvent.
b. The Diels-Alder product conserves every atom present in the reagents, whereas the Grignard does not.
c. The Diels-Alder uses maleic anhydride, which by definition has no water and therefore less water waste is generated. The Grignard, conversely, generated a lot of water waste.
d. The Diels-Alder uses alkenes which are highly flammable and reduces their flammability by forming a six-membered ring.
Explanation / Answer
options a , b ,c
Green chemistry prefers
i)prevention of waste
ii) atom economy
iii)less hazardous chemicals usage
iv) safer solvents
among other aspects.
Thus Diels -Alder uses no solvent, no wastage
atoms are conserved
