CH3 MeOH CH3 CH3 CH3 H3C H3C H3C Br Alkyl halides undergo nucleophilic substitution and elimination reactions. When the kinetics of the reaction are measured, if the rate of the reaction is found to be dependent only upon the concentration of the alkyl halide the reaction is first order. The substitution reaction is thus termed SN1, and the elimination reaction is termed E1. These reactions are unimolecular and occur in two steps. The first step is rate-limiting and involves the loss of the leaving group to form a carbocation. In the second, fast, step the nucleophile adds to the carbocation in the SN1 reaction or elimination occurs to give an alkene in the E1 reaction. Because the carbocation is planar, the nucleophile can add to either face and therefore racemization is usually observed although solvent effects can influence this somewhat. E1…The following reaction conditions gives a mixture of two addition products A and B shown below. CI.

- Acyl transfer (nucleophilic substitution at carbonyl) reactions proceed in two stages via a "tetrahedral intermediate." Draw the tetrahedral intermediate as it is first formed in the following reaction. You do not have to consider stereochemistry. Include all valence lone pairs in your answer. Do not include counter-ions, e.g., Na+, I-, in your answer. In cases where there is more than one answer, just draw one.The high reactivity of alkyl halides can be explained in terms of nature of C-X bond which is highly polarized covalent bond due to large difference in the electronegativities of carbon and halogen atom. This polarity is responsible for the nucleophilic substitution reactions of alkyl halides which mostly occur by Swa and Swa mechanisms. Sy reaction is a two-step process and in the first step, R-X ionizes to give carbocation (slow process). In the second step, the nucleophile attacks the carbocation from either side to form the product (fast process). In Swi reaction, there can be racemization and inversion. Swi reaction is favored by heavy (bulky) groups on the carbon atom attached to halogens. i.e., R,C-X>R;CH-X>R-CH,X>CH,X. In Sna reaction, the strong nucleophile OH attacks from the opposite side of the chlorine atom to give an intermediate (transition state) which breaks to yield the product (alcohol) and leaving (X) group. The alcohol has a configuration opposite to that of the…[Review Topics] [References) In both series below the three aromatic compounds illustrated undergo the electrophilic substitution reaction shown NHČCH3 Reaction: Bromination Which compound (A, B, or C) reacts the fastest?
