There are three different possible structures (known as isomers) of a dibromoethene molecule, C2H2Br2 . One of them has no net dipole moment, but the other two do. Draw Lewis structures for each of these structures. Include H atoms. nonpolar C2H2Br2 structure (one structure) polar C2H2Br2 structures (two structures)

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
