Which outcome occurs when a UV photon interacts to disrupt overlapping electron orbitals?

A)Bond energy is overcome causing dissociation
B)Molecular vibration increases reducing temperature
C)Catalyst active site becomes more selective
D)Nuclear spin changes become more coherent

💡 Explanation

Bond dissociation occurs because absorption of a sufficiently energetic photon induces electronic transition. It breaks the **covalent bond**, therefore bonds are overcome and fall apart, rather than inducing vibration/spin because energy overwhelms bond energy.
