The hydrogen bond between $$F^{-}$$ and $$CHCOOH$$ is very strong and its strength may be analysed by setting up a Born-Haber cycle with the following data $$(in\ kJ/mol)$$: Lattice energy of $$KF. CH_{3} COOH, 734$$; enthalopy of vaporization of $$CH_{3}COOH,20$$; enthalpy of solution of $$KF, 35;$$ solvation energy of $$K^{+} (g), -325$$; solvation energy $$F^{-}, -389$$; enthalpy of formation of $$KF. CH_{3} COOH (s)$$ from $$KF(s)$$ and $$CH_{3} COOH(I),-25$$. FInd the energy of the hydrogen bond between $$F^{-}$$ and $$CH_{3} COOH$$ in the gas phase $$(in\ kJ/mol)$$
