Acc. to Law of Conservation of Mass
Mass of reactants=Mass of Products
Let mass of Oxygen be x.
So,
50.6+x=452
x=452-50.6
=401.4 g

One mole of acetyl chloride was mixed with one mole of dimethylamine. After the reaction is complete, what species can be found
fredd [130]

Answer:

N,N-dimethylacetamide is formed.

Explanation:

  • It is an example of a nucleophilic addition-elimination reaction. Here dimethylamine acts as a nucleophile.
  • In the first step, dimethyl amine gives nucleophilic addition reaction at carbonyl center of acetyl chloride.
  • In the second step, removal of Cl atoms occurs.
  • In the third step, deprotonation takes place from amino group to produce N,N-dimethylacetamide.
  • Full reaction mechanism has been shown below.
