Why bond dissociation energy of d2 > h2 > f2............... ?
@ himanshu flourine bond dissociation enthalpy is lower than the other two . reason – flourine have a very small nucleaus and it contains 3 lone pairs , there is a great repulsion among them , and other two having the vacant orbitals to keep their lone pairs , so, there is not much repulsion among them . so, flourine will breaks easily . KINDLY MENTION WHAT IS D2 ?? hope it clears now
