Question

Is it chloropropane for chloro prop 2 in which is more reactive towards sn1 mechanism?

Answer 1

SN1 reaction involves the formation of carbocation intermediate. More the stability of carbocation more is the reactivity of alkyl/aryl halides towards SN1 reaction. The intermediate carbocations formed by given halides as: Thus, C6H5C(CH3)(C6H5)Br is most reactive towards SN1 reaction.

Answer 2

Answer:

According to me , we should compare carbo cation stability which is formed as an intermediate.

So the 4th compound (tertiary butyl chloride) should be in top in order of reactivity.

But how to compare other three compounds.
