1a. Rank the following substrates from most (1) to least reactive (3) in an SN2 reaction. Explain the reason for your choice.- **Substrate A:** A cyclohexane ring with a bromine atom attached at the 1-position.- **Substrate B:** A cyclohexane ring with a bromine atom attached at the 2-position.- **Substrate C:** A cyclohexane ring with a bromine atom attached at the 3-position.1b. Rank the following substrates from most (1) to least reactive (4) in an SN1 reaction. Explain the reason for your choice.- **Substrate A:** A tertiary alkyl bromide structure.- **Substrate B:** A primary alkyl bromide structure.- **Substrate C:** An allylic bromide structure with a degree of unsaturation.- **Substrate D:** A secondary alkyl bromide structure.**Explanation:**- **SN2 Reaction:** Reactivity generally decreases from primary to tertiary substrates due to steric hindrance.- **SN1 Reaction:** Reactivity generally increases from primary to tertiary substrates due to the stability of the carbocation formed during the reaction. Allylic and benzylic carbocations also exhibit high stability.

Sn2 reaction is bimolecular nucleophilic substitution reaction. Sn1 is unimolecular nucleophilic substitution reaction In Sn2 reaction less hindered substrate is most reactive because it is single step reaction both attack of nucleophile and departure of leaving group takes place in same step. In sn1 reaction , more hindered substrate most reactive because it undergoes through carbocation intermediate, and more substituted carbocation is more stable.
