The method could be improved by heating sulfuric acid solution and add copper carbonate into the solution of sulfuric acid. Add the copper carbonate until it is present in excess amount. After that filter the extra amount of copper carbonate so in this way the blue copper sulfate crystals are produced.

Photochemical chlorination of 1,2-dibromoethane gives a mixture of two stereoisomers of C2H3Br2Cl. Write their structural formul

Sever21 [200]

Answer:

Enantiomers

Chiral

Yes they will be formed in equal amount.

Explanation:

The Two possible stereo isomers are formed due to generation a chiral center in the molecule.

There will be a carbon with all the four groups different.

The two isomers will be called as enantiomers, which are non super-imposable mirror image of each other.

They are named as "R" or "S'" based on the selection rule.

The IUPAC names are also given in the figure.

The two isomers will be formed in equal amount as during photochemical chloriantion of a compound free radicals are generated (which are trigonal planar) and the other radical may attack from either side (front side or back side) giving the two stereo-isomers.
