The order of reactivity of the halides are R − I > R − Br > R − Cl > R − F Conditions of the SN2 Chemical Reactions There is a requirement of the strong nucleophile to undergo SN2 reaction. The reaction takes place in the presence of solvents that are polar aprotic suc...
Reactivity of alkyl halide towards SN1 and SN2 reactions depends on various factors such as steric hindrance, stability of intermediate or transition state and polarity of solvent. SN2 reaction mechanism is favoured mostly by primary alkyl halide then secondary and then tertiary. This order is ...

SN1reaction follows first-order kinetics, that is, the rate of reaction depends on the concentration of only one reactant, which is tert-butyl bromide and is independent of the concentration of hydroxide ion. Rate $=k\left[\left(\mathrm{CH}_{3}\right)_{3} \mathrm{CBr}\right]$. Hence...

“big barrier” to the SN1 reaction as beingcarbocation stability, That is, any factor which leads to the increased stability of a carbocation intermediate will increase the rate of the SN1. That’s why this pathway tends to be favored by tertiary alkyl halides, since the order of ...
SN1 reaction has a carbocation as intermediate, so the nucleophile can attack from both sides (every carbocation is planar). Because of that, I think that the reaction occurs at the same velocity. It it had been a SN2 reaction, the cis would have reacted faster (because SN2 is a one ...

For reactivity using an Sn2 mechanism, primary >> secondary >> tertiary carbon centers. On the other hand, Sn1 reactions are unimolecular in rate of reaction and have a step-wise mechanism. This process first involves bond cleavage by the LG to generate a carbocation intermediate.The stability...
