WebThere are two hydrogen bond donors (H) and two hydrogen bond acceptors in oxygen lone pairs (O:). This means that any individual water molecule is involved in four hydrogen bonds. However, if you extrapolate that to the whole lattice, you cannot double count the acceptors and the donors, both are needed for a H-bond. WebThe Bond Enthalpy is the energy required to break a chemical bond. It is usually expressed in units of kJ mol -1, measured at 298 K. The exact bond enthalpy of a particular …
