What are the 3 key factors that affect the rate of the SN2 reaction?
structure of the alkyl halide.
Which factors decides the reactivity of alkyl halides?
Experiments have shown that the strength of carbon halogen bond is the main factor which decides the reactivity of alkyl halides.
What is the reactivity order of alkyl halides in SN2?
In general, the order of reactivity of alkyl halides in SN2 reactions is: methyl > 1° > 2°. The 3° alkyl halides are so crowded that they do not generally react by an SN2 mechanism.
Why are alkyl halides considered to be reactive compounds to nucleophiles?
Explanation: Alkyl halides are considered to be very reactive compounds towards nucleophile because they have an electrophilic carbon & a good leaving group as we go down the periodic table, halides that are larger in size will also be able to distribute their charge over a larger volume, making them less reactive ( …
How does the structure of alkyl halide affect the rate of SN2 reaction?
In order of decreasing importance, the factors impacting SN2 reaction pathways are the structure of the alkyl halide, the strength of the nucleophile, the stability of the leaving group, and the type of solvent. The formation and stability of the carbocation intermediate strongly influence the SN1 mechanism.
Which alkyl halides are most reactive?
By either mechanism, allylic and benzylic halides are highly reactive. The alkyl halide reactivity order is RI > RBr > RCl.
Which alkyl halide has the highest reactivity?
The high reactivity of alkyl halides can be due to the polarisation of carbon -halogen bonds. Due to this, carbon develops a partial positive charge and halogens develop a partial negative charge. Thus, bromopropane is the most reactive compound.
Which alkyl halide has the lowest reactivity for a particular alkyl group?
Chemical Reactivity To react with the alkyl halides, the carbon-halogen bond has got to be broken. Because that gets easier as you go from fluoride to chloride to bromide to iodide, the compounds get more reactive in that order. Iodoalkanes are the most reactive and fluoroalkanes are the least.
