In the reaction R_Br + Cl- dimethyl formamide R_Cl + Br- What is the order of the relative rates of - Chemistry - Haloalkanes and Haloarenes

Question

In the reaction
R_Br + Cl- dimethyl formamide
R_Cl + Br-
What is the order of the relative rates of reaction of methyl
bromide (1), ethyl bromide(2), isopropyl bromide(3), and tert butyl
bromide (4)

na · Accepted Answer

This reaction follows
SN2 mechanism
The order of reactivity if alkyl halides in
SN2 mechanism is
10>20>30
So the order is

methyl bromide > ethyl
bromide> isopropyl bromide > tert butyl
bromide

In the reaction R_Br + Cl- dimethyl formamide R_Cl + Br- What is the order of the relative rates of reaction of methyl bromide (1), ethyl bromide(2), isopropyl bromide(3), and tert. butyl bromide (4) .

In the reaction

R^_Br + Cl^- dimethyl formamide R^_Cl + Br^-

What is the order of the relative rates of reaction of methyl bromide (1), ethyl bromide(2), isopropyl bromide(3), and tert. butyl bromide (4) .
