Substitution reactions of alkyl halides purpose: to examine the relative rates of various alkyl halides under sn1 and sn2 conditions we will be examining sn2 reactions with the finkelstein reaction the conditions for this are nai in acetone. Some of the most important information concerning nucleophilic substitution and elimination reactions of alkyl halides has come from studies in which the structure of the alkyl group has been varied as noted earlier, the carbon bonded to the halogen is sp 3 hybridized in all the alkyl halides discussed here.

Alkyl halides are a carbon with one of the hydrogens replaced with a halogen (fluoride, chlorine, iodine, bromine, or astatine) these alkyl halides are important because the halogens are a good leaving group that can easily.

Chem 230l laboratory report reactivity of some alkyl halides - download as word doc (doc / docx), pdf file (pdf), text file (txt) or read online chem 230l laboratory report reactivity of some alkyl halides. The systematic way of naming alkyl halides is to name the halogen as a substituent, just like an alkyl group, and use numbers to indicate the position of the halogen atom on the main chain the name of the halogen as a substituent comes from the stem of the element’s name plus the ending –o, so the substituent names are fluoro-, chloro-.
89 industrial preparation and use of alkyl halides, alcohols, and ethers 365 the conditions of this reaction (initiation by heat or light) suggest the involvement of free- radical intermediates (sec 56c.

Reactivities of some alkyl halides
Alkanes are non-aromatic while some of the alkyl halides have an associated smell nomenclature of alkyl halides halogen imparts reactivity to alkyl halides. In order to understand why some combinations of alkyl halides and nucleophiles give a substitution reaction, whereas other combinations give elimination, and still others give no observable reaction, we must investigate systematically the way in which changes in reaction variables perturb the course of the reaction. Prepartion of alkyl chlorides by the treatment of alcohols with thionyl chloride (socl2) alkyl halides will react with some metals (m0) in ether or thf to.
