Title: Nucleophillic Substitution Reaction

This lab experimented on the chemical answers of the chemicals that undergoes SN1 or SN2 reaction. Nine dissimilar compounds were disposed to be examined with two reagents ? NaI in acetone and AgNO3 in neutral spirits. The SN1 reaction happens in AgNO3 in ethanol reagents, and SN2 reaction is in NaI in acetone. Procedure: Following the lab manual.

This is because bromobenzene is very stable, and contains allylic and vinyllic bromine, which is as well as very stable, and cannot be a good nucleophile. Bromocyclopentane reacts under SN1 and SN2, but it shows a faster reaction in AgNO3/ethanol reagent, that is SN1. This is because bromocyclopentane is junior- grade bromine, and have big steric strain, since it is a cyclic compound. The bigger steric in a molecule, the harder it is for the nucleophile to attack the expiration group (-Br) from the opposite fonts, therefore, SN2 reaction is slower than SN1 for bromocyclopentane. From this reaction, precipitation occurs to fracture out AgBr in ethanol and NaBr in acetone. Bromocyclohexane, on the another(prenominal) hand, shows no reaction in SN2 reagent, but almost an prompt reaction in SN1 reagent. The reasons are very some(prenominal) the selfsame(prenominal) with bromocyclopentane above ? steric strain.

As bromoc yclohexane is bigger than that of bromocyclo! pentane, the steric in bromocyclohexane is too much for the nucleophillic attack from the opposite side of the leaving Bromine. In the end, whole SN1 reaction could pass this nucleophillic substitution. 2-bromobutane undergoes a slow SN2 reaction, but shows an spry result in SN1 reaction. As 2-bromobutane consists of secondary bromine, both SN1 and SN2 could happen. The accrue for this reaction should be NaBr and AgBr. On the other hand, 2-chlorobutane undergoes an even...
