WebHydrogen bonds (H-bonds) are a specific type of electrostatic interaction between a proton attached to an electronegative atom (such as N or O) and a lone pair of electrons on an electronegative atom such as N, O, or F. The former is called the H-bond donor, the latter the H-bond acceptor. WebScience. Chemistry. Chemistry questions and answers. Use bond energies to estimate ΔH for the combustion for three moles of acetylene (H-C≡C-H). (Use the bond energy values in this table.)
