Description Define The Following Based On The Information Below Sn1 And Sn2 Methy Cation Primary Cations Tertiary Ca 1 (76.93 KiB) Viewed 30 times

Description Define the following based on the information below: SN1 and SN2, methy cation, primary cations, tertiary carbocations, aprotic solvents, protic solvents, good nucleophiles, poor nucleophiles, carbocation rearrangements, steric hindrance, inversion of configuration, racemization, methyl halide, primary halide, secondary halide, and tertiary halide. Type of Alkyl Halide Methyl CH3 X Primary RCH₂X Secondary R₂ CHX Tertiary R, CX Substitution at a stereocenter SN2 SN2 is favored. SN2 is favored. SN2 is favored in aprotic solvents with good nucleophiles. SN2 does not occur because of steric hindrance around the reaction center. Inversion of configuration. The nucleophile attacks the stereocenter from the side opposite the leaving group. SN 1 SN1 does not occur. The methyl cation is so unstable, it is never observed in solution. SN1 rarely occurs. Primary cations are so unstable, that they are never observed in solution. SN1 is favored in protic solvents with poor nucleophiles. Carbocation rearrangements may occur. S1 is favored because of the ease of formation of tertiary carbocations. Racemization is favored. The carbocation intermediate is planar, and attack of the nucleophile occurs with equal probability from either side. There is often some net inversion of configuration.
