WebApr 11, 2024 · The reaction rates of different chemicals primarily depend on the bombardment rate of molecules involved. This collision rate depends on many other variables that can be manipulated to affect the rates of reactions. Manipulating these factors either induces a positive or negative yield in the response. These factors include a … WebThe reactivity range encompassed by these reagents is over 5,000 fold, thiolate being the most reactive. Note that by using methyl bromide as the reference substrate, the complication of competing elimination reactions is avoided.

14.3. Substituent Effects Organic Chemistry II - Lumen Learning

WebIntroduction. There are two main effects of substituents. The substituent will affect the rate of reaction (aka reactivity) of the ring, and it will also affect the position of attack (called “directing effects”) on the ring by the incoming electrophile. Thus we need to answer the following questions: Does the substituent activate or deactivate the aromatic ring? WebThe meaning of REACTIVITY is the quality or state of being reactive.

When we talk about chemical reactions, it is a given fact that rate at which they occur varies by a great deal. Some chemical reactions are nearly instantaneous, while others usually take some time to reach the final equilibrium.
