Vedclass · Answer

(B) Atom economy is defined as the ratio of the molecular weight of the desired product to the sum of the molecular weights of all reactants,expressed as a percentage. Reaction $B$: $C_2H_4 + H_2 \xrightarrow{Ni} C_2H_6$ is an addition reaction where all atoms of the reactants are incorporated into the product. Atom economy = $\frac{	ext{Mol. wt of } C_2H_6}{	ext{Mol. wt of } (C_2H_4 + H_2)} 	imes 100 = \frac{30}{30} 	imes 100 = 100 \%$. Since the atom economy is $100 \%$,this reaction exhibits the best atom economy among the given options.

Which of the following reactions exhibits good atom economy according to the principles of green chemistry?
