The bond that describes an interaciton between two orbitals that is not symmetrical about a line between the two atoms nuclei is called

Pi bond

Explanation:

Pi bond is the type of covalent bond which results from formation of molecular orbital by the side-to-side overlap of the atomic orbitals along the plane perpendicular to the line which connects nuclei of the two atoms in which the bond is formed. It is denoted by symbol π.

The bond is not symmetrical to the internuclear axis and on rotation the axis, the bond breaks.

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.
