Question

1) C2H2 ------------> CHBr - CHBr 2) C2H2 -------------> CH2 = CH - Br

Answer 1

С2H2 + Br2 ----> ...
C2H3 + HBr ----> ...

Answer 2

1) The reaction C2H2 -> CHBr + CHBr involves the addition of two bromine atoms to an acetylene molecule (C2H2). This reaction is known as bromination of acetylene. The double bond in acetylene is broken, and two bromine atoms are added to the carbon atoms, resulting in the formation of two molecules of CHBr. This reaction is an example of an addition reaction, where atoms or groups of atoms are added to a molecule.

2) The reaction C2H2 -> CH2 = CH-Br involves the addition of a bromine atom to one of the carbon atoms in the acetylene molecule (C2H2). This reaction is known as bromination of alkynes. The double bond in acetylene is broken, and a bromine atom is added to one of the carbon atoms, resulting in the formation of a molecule with a double bond between the two carbon atoms and a bromine atom attached to one of the carbon atoms.

These reactions are commonly used in organic chemistry to introduce bromine atoms into molecules and can be used for the synthesis of various organic compounds. The specific conditions and reagents used in these reactions may vary depending on the desired outcome and the specific reaction conditions.
