WebFeb 9, 2024 · For a strong acid such as hydrochloric, its total dissociation means that [HCl] = 0, so the mass balance relationship in Equation 13.3.3 reduces to the trivial expression Ca = [Cl-]. Any acid for which [HA] > 0 is by definition a weak acid. Similarly, for a base B we can write (13.3.4) C b = [ B] + [ H B +] Note WebNov 18, 2024 · Covalent bonds rely on sharing of a pair of electrons between two atoms, an electron each from both atoms involved. The better the sharing, the stronger the covalent bond formed. This sharing is reflected in the valence shell orbital overlap that occurs between the two atoms, when a more effective overlap occurs, a stronger covalent bond …

WebMay 21, 2024 · The strength if an electron-pair donor ( Lewis base) depends on the availability of its sharable electrons. Methyl groups are electron-donating. They increase the electron density around the N atom. Thus, Lewis base strength increases in the order H2N:- < CH3NH:- < (CH3)2N:- Answer link WebSodium ethoxide is a strong base and its reaction with a secondary alkyl halide will mainly yield an elimination product through E2 mechanism which can also be seen from the reaction equation. The rate of the E2 reaction depends both on the substrate and the base and therefore the following changes will be observed: a) The rate doubles

WebA conjugate acid, within the Brønsted–Lowry acid–base theory, is a chemical compound formed when an acid donates a proton ( H +) to a base —in other words, it is a base with a hydrogen ion added to it, as in the reverse reaction it loses a hydrogen ion. WebNow the question is how to determine which is stronger base for that we compare the strength of conjugate acid that is H2O (Water) and NH3 (Ammonia). Water is neutral whereas ammonia is a weak base (even less acidic). Stronger conjugate acids have weaker conjugate base and vice versa . Therefore, NH2- is a stronger base.
