11. A pentafoil knot prepared using dinamic covalent chemistry has been reported. 12. Not all irreversible inhibitors form covalent adducts with their enzyme targets. 13. Compounds in its preferred oxidation state of + 4 are covalent . 14. Most of the ordinary compounds of bismuth are covalent in nature. 15. The original theoretical calculations had been carried out by covalent bonds. 16. The atoms are much more strongly bound with a covalent bond. 17. The chemists might create new ones like single or triple covalent bonds. 18. Phase III is typically associated with large-deformation covalent bond stretching. 19. Transition metal complexes are generally bound by coordinate covalent bonds. 20. Unlike pure ionic bonds, covalent bonds may have directed anisotropic properties.
