Question

describe what you observed during the lab at the following times: how long did your addition of the acid mixture take? how much ethanol did you use for the recrystallization? what did your nitroacetanilide crystals look like? how long did you dry the final solid before taking the mass and melting point?

Answer 1

The addition of acid mixture would take around five minutes, and a solid nitroacetanilide would form.

Nitroacetanilide  is a chemical compound which is a nitro derivative of acetanilide. There are two other isomers of nitroacetanilide, 2-nitroacetanilide and 3-nitroacetanilide.

   4-Nitroacetanilide is used as in intermediate in the production of some dyes. Nitroacetanilide is also referred to as p- Nitroacetanilide or Para Nitroacetanilide.

    As mentioned, it has two isomers - isomers are two or more than two different compounds having same formula but different arrangements of atoms.

   For the given condition, the time for mixture of acid would take place for 5 minutes. 2% of ethanol will be used for the recrystallization, and it would need several minutes to dry and get the solid nitoacetanilide.
