Which carbocation formed from CH₃CH₂CH(Cl)CH₃ via heterolytic cleavage is stabilized by hyperconjugation after a possibl

Cleavage at C-Cl forms CH₃CH₂CH⁺CH₃ (secondary). Hyperconjugation with adjacent C-H bonds stabilizes it.

Which intermediate is least likely to form during the heterolytic cleavage of CH₃CH₂CH₂Cl in a polar solvent?

Heterolytic cleavage of CH₃CH₂CH₂Cl forms CH₃CH₂CH₂⁺ (carbocation) and Cl⁻. Free radicals require homolytic cleavage, less favored in polar solvents.

Which intermediate is most likely to form during heterolytic cleavage of CH₃CH₂CH(Cl)CH₃ in a polar solvent?

Heterolytic cleavage of C–Cl in CH₃CH₂CH(Cl)CH₃ forms CH₃CH₂CH⁺CH₃ (secondary carbocation) and Cl⁻, favored in polar solvents.

Which carbocation is most likely to rearrange to a more stable form if formed from CH₃CH₂CH₂CH₂CH₂Cl via heterolytic cle

Cleavage at CH₂Cl forms CH₃CH₂CH₂CH₂CH₂⁺ (primary). A hydride shift to CH₃CH₂CH₂CH⁺CH₃ (secondary) increases stability via hyperconjugation.

Which carbocation formed from CH₃CH₂CH₂CH(Cl)CH₃ via heterolytic cleavage is most stabilized by the inductive effect?

Cleavage at C-Cl forms CH₃CH₂CH₂CH⁺CH₃ (secondary). A hydride shift to CH₃CH₂CH⁺CH₂CH₃ (secondary) is equally stable, but +I effect from alkyl groups favors it slightly more.

Which intermediate is most stabilized by the inductive effect of alkyl groups in CH₃CH₂CH(CH₃)CH₂Cl upon heterolytic cle

Heterolytic cleavage of CH₃CH₂CH(CH₃)CH₂Cl at CH₂Cl forms CH₃CH₂CH(CH₃)CH₂⁺ (primary), but a hydride shift forms CH₃CH₂C⁺(CH₃)CH₃ (tertiary), stabilized by the +I effect of three alkyl groups.
