Question

заполните пропуски: С4Н4 - С2Н2 - ... - ... - анилин

Answer 1

3С2Н2= С6Н6 реакция тримеризации

С6Н6 + HNO3= C6H5NO2 + H2O из бензола получаем нитробензол

C6H5NO2 + 3 Fe + 6 HCl = C6H5NH2 + 3 FeCl2 + 2H2O

Answer 2

Chemical Formula Puzzle

The chemical formula puzzle seems to be asking for the missing compounds between C4H4 and aniline (C6H5NH2).

C4H4 is the chemical formula for butadiene, which is a colorless gas with a mild aromatic odor. It is an important industrial chemical used in the production of synthetic rubber.

C6H5NH2 is the chemical formula for aniline, which is an organic compound with the formula C6H5NH2. It consists of a benzene ring attached to an amino group. Aniline is used in the production of various chemicals, including dyes, pharmaceuticals, and rubber processing chemicals.

The missing compounds between C4H4 and aniline are C4H4 - C2H2 - C2H2 - C6H5NH2.

This sequence suggests that two molecules of acetylene (C2H2) are missing between butadiene and aniline.
