Answer to Question #104568 in Physical Chemistry for Amit Panchal

Question

Which one of the following would undergo faster SN2 reaction? Explain

CH3 – CH = CH – Cl
or
CH3CH2CH2 – Cl

Answer 1

Solution.

Chlorpropane will undergo a faster SN2 reaction than chlorpropenyl, because SN2 reactions occur most quickly for primary alkanes. Vinyl alkyl halides practically do not enter into this mechanism due to the interaction of the non-white electron pair of the halogen and PI- electrons of the multiple bond (+M-effect).

Answer:

Chlorpropane
