For example, the SN2 reaction. HO⁻ + (CH₃)₃C-Br → HO-C (CH₃)₃ + Br⁻. is much slower than the SN2 reaction. HO⁻ + H₃C-Br → HO-CH₃ + Br⁻. because the bulky CH₃ groups hinder the ability of HO⁻ to reach the carbon atom. ( 13 votes) incompatibility\\u0027s v8

"A solvated electron is a free electron in (solvated in) a solution, and is the smallest possible anion. Solvated electrons occur widely. Often, discussions of solvated electrons focus on their solutions in ammonia, which are stable for days, but solvated electrons also occur in water and other solvents – in fact, in any solvent that mediates outer-sphere electron transfer. The solvated electron is responsible for a great deal of radiation chemistry. " - Solvate chemistry
