Question

How are SN1 reactions solved?

Answer 1

follow the steps to analyse SN1 condition and then solve.

Explanation:

(1) SN1 reactions involve the formation of a carbocation, thus the basic need is the presence of a polar protic solvent so that carbocation can easily form.

(2) maximum hindrance present at the key carbon helps in faster leaving of the leaving group, so is favorable.

(3) rate of reaction is `prop` stability of the carbocation formed

(4) rate of reaction is `prop` leaving ability of the leaving group.

(5) usually, a weak base or nucleophile is needed so that acid- base reaction can be prevented.

SO, CHECK IF THE ABOVE CONDITIONS ARE SATISFIED, THAN SN1 IS FAVOURABLE.

However, the requirments for E1 reactions are also same, but the basic difference in E1 and SN1 is that SN1 is favourable at low temperature, while E1 is favoured at high temperature.

Good luck!
