Primarygun Posted December 25, 2006 Share Posted December 25, 2006 the single bond enthalpy of oxygen and sulphur are +142 and +264 respectively, why oxygen atom has a much smaller single bond enthalpy than sulphur atom ?may anyone please expalin the large difference?

chemhelper Posted January 8, 2007 Share Posted January 8, 2007 I am confused by your question. The bond enthalpies of elements vary depending on what other element the atom bonds to. For example, the enthalpy (i.e. bond strength) of an O-H bond is going to be different than an O-C bond. Also, oxygen should have a stronger bond enthalpy than sulfur because it has a much smaller radius than sulfur. ---------- Have homework questions in chemistry, math or physics?
