Alkyl Halide Reactivity Home Chemistry

2012-8-27  Alkyl Halide Reactions. The functional group of alkyl halides is a carbon-halogen bond, the common halogens being fluorine, chlorine, bromine and iodine. With the exception of iodine, these halogens have electronegativities significantly greater than carbon. Consequently, this functional group is polarized so that the carbon is electrophilic

4.16: Nucleophilic Substitution in Synthesis: Alcohols

2021-6-10  For example, an alkyl halide might be transformed into an alcohol, or into an ether. The trouble is, these seemingly simple steps can be very difficult. That's because the hydroxide needed to make an alcohol from an alkyl halide is really quite basic. So is the alkoxide that would be needed in order to turn an alkyl halide into an ether.

The first step, ion-ization of the alkyl halide to a carbocation, is the rate-limiting step and thus has the transition state of highest free energy. The rate of this step is the rate at which the alkyl halide reacts. The

4.16: Nucleophilic Substitution in Synthesis Alcohols

2020-8-12  4.16: Nucleophilic Substitution in Synthesis Alcohols and Ethers. Nucleophilic substitution reactions can be useful in organic synthesis. Mostly they are used for the interconversion of functional groups. For example, an alkyl halide might be transformed into an alcohol, or into an ether. The trouble is, these seemingly simple steps can be

Chemistry 254 Lab Experiment 1: Qualitative Organic

2004-7-16  Procedure: In each test tube, place 2 mL of Lucas reagent in a small test tube and add 3-4 drops of the test alcohol. Stopper the test tube and shake it vigorously. Tertiary, benzylic, and allylic alcohols give an immediate cloudiness in the solution as the insoluble alkyl halide separates from the aqueous solution.
