I don't think it's a particularly good question. Explosions have as much to do with kinetics as they do with thermodynamics, and in thermodynamics there are entropic as well as enthalpic factors to consider. Kinetic and thermodynamic stability are only partially related. Explosive materials tend to also produce large volumes of gasses. That often but not always goes hand in hand with large reaction enthalpies. The release of heat alone will not create an explosion - high reaction rates are also needed so that the heat is produced rapidly enough to rapidly expand gas and create large pressures. There are lots of fuels that produce great amounts of heat, but are not explosive because the reaction kinetics do not favor it.
Were I answering the question, I'd probably say something like - all things being equal, highly exothermic reactions are also usually highly exergonic, especially at high temperatures when the entropy is also large (as it would be for any reaction that produces a large amount of gas). Highly exergonic reactions also have - all things being equal, again - large reaction rates. Explosions are generally characterized by producing large amounts of heat, which contributes to the production of rapidly expanding gas. But things are rarely equal, so it is inappropriate to say that all highly exothermic reactions give rise to chemical explosions. It would probably be more appropriate to say that all reactions that give rise to chemical explosions are highly exothermic (need a Venn diagram?). This may not be always true, either, but I can't think of an exception off the top of my head...
