E) A polar covalent compound yields a large percentage of ions in the solution. 17) Which one best describes a strong electrolyte?
Covalent molecules made of only one type of atom, like hydrogen gas (H2), are nonpolar because the hydrogen atoms share their electrons equally. Molecules made of more than one type of covalently bonded nonmetal atoms, like carbon dioxide gas (CO2), remain nonpolar if they are symmetrical or if their atoms have relatively equal pull.

Sep 19, 2019 · High-throughput screening is a popular approach for hit-finding but if the objective is to find covalent ligands then it is likely that any molecules containing potential reactive groups will have been removed from the screening collection. Thus the most common strategy is to incorporate an electrophile into an already optimized reversible ligand.

Jun 03, 2013 · As you know, in an ionic compound, the charge of the ion is the oxidation state. For example, the o.s. of Na in NaCl is +1. However, for covalent compounds, the more electronegative atom is assigned a negative oxidation state (because it has a higher affinity for electrons) while the less electronegative atom is assigned a positive oxidation state.
