Homework Answers
a) SN2 reaction requires nonpolar solvent,So, MeOH is not suitable for this reaction.
b) Protic solvent is good for SN1 reaction and some times SN2 with secondary alcohol needs protic solvent.So, hexane is not a good solvent fot SN2/SN1.
c) SN2 reaction requires nonpolar solvent,So, Acetone is suitable for this reaction.
d) C-I bond can easily breakable than C-Cl bond.So, Iodide is better leaving group than the Chloride.
e) Tosylate can be stabilized by resonance than the iodide.so, that tosylates are better leaving groups than iodides.

A student attempted to carry out a substitution reaction using molecule as the substrate. The resulting product was molecule. Which nucleophilic substitution occurred --- S_N1 or S_N2 How can you tell The molecule here cannot be used as a substrate for an E2 reaction, but can be for an E1 reaction. Explain why. Be specific --- explain why an E2 reaction cannot occur and how an E1 reaction could occur. Where does the nucleophile attack in an S_N2 reaction Backside...

hypothesize why a tertiary alcohol is a good solvent for an sn2 reaction where CsF is the nucleophile and iodide is the leaving group there are various electrophiles that iodide is leaving from who's identities don't seem to matter. from everything I've learned up to now protic solvents are NOT good solvents for sn2 rxns. there have been numerous articles on a research project where 18F is being used for radiolabeling in biological systems and they used tert-amy-alcohol for the...

sodium p toluenesulfonate in aqueous ethanol.
Indicate which reaction will occur faster. Explain your reasoning. Select the single best answer Reaction of 1-chlorobutane with sodium iodide or sodium p-toluenesulfonate in aqueous ethanol Sodium iodide will react faster because the leaving group encounters less sterle hindrance. Sodium iodide will react faster because the intermediate is more stabilized in the solvent. Sodium p-toluenesulfonate will react...
