Question

What formula of a compound is formed when ethene gas reacts with bromine vapour to form an organic compound

Answer 1

Answer:

Ethene reacts with liquid bromine to give 1,2-dibromoethane.

Explanation:

1,2-dibromoethane is formed when ethane interacts with liquid bromine. The reaction between ethene with bromine also produces a symmetrical alkyl halide molecule. In the ethene molecule, two bromine atoms are linked to the two carbon atoms. This reaction can be carried out at room temperature or at lower temperatures.

Bromine to ethene addition is an electrophilic addition process. Bromine molecule (Br2) is normally not an electron deficient chemical. Bromine molecules, on the other hand, become polarised due to greater electron density in the double bond of ethene. The bromine molecule's most closest atom to the double bond is positively charged (Br+), while the other bromine atom is negatively charged (Br-).
