WebA variety of amine bases can be bulky and non-nucleophilic. 2. Nucleophiles will not be good bases if they are highly polarizable. I- is the best example of this. Great nucleophile, really poor base. Why do we care about strong nucleophiles? Organic chemistry is all about reactions.

WebIn chemistry, a hydride is formally the anion of hydrogen (H −). The term is applied loosely. At one extreme, all compounds containing covalently bound H atoms are called hydrides: water (H 2 O) is a hydride of oxygen, ammonia is a hydride of nitrogen, etc.For inorganic chemists, hydrides refer to compounds and ions in which hydrogen is covalently attached … Web5 jul. 2024 · The factors that favor S N 2 mechanism and increase the rate of S N 2 reactions are: A strong nucleophile (small in size, less electronegative, negatively charged species).
