Question

CA 19 which of the following statement(s) apply to the SN2 mechanism A) It occurs with inversion of stereochemistry B) It occurs with racemization of stereochemistry C) It proceeds through a carbocation intermediate D) Works best with strong nucleophile 2 cirle the compound you would expect to absorb the lowest energy inht oto 3. Circle each of the following compounds that are aromatic. (8) 4. (4) Circle any of the following compounds that you would expect to work as electrophiles for an SN1 reaction. Br

Explanation / Answer

1. SN2 mechanism takes place with inversion of configuration. Hence the correct option is (A).

2. The compound which have more conjugated double bonds will have largest wavelength (lambda Max) and hence lowest energy. Therefore, the Triphenyl methane will have lowest light energy.

3. Cyclopropenyl cation is aromatic.

4. 2-Chloro-2,3-dimethylpentane will act as good electrophile for SN1 reaction because it will give most stable carbocation.
