WebFeb 19, 2016 · Steric hindrance is the hindrance to a reaction that is caused by large groups in a molecule. 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) WebCation exchange is illustrated by the equilibrium: n(RSO 3-H +) + Mn + → (RSO 3-)nMn + + nH + Ion-exchange selectivity (bonding to the stationary phase of the column) depends on the affinity of the resin for the cation (or anion) in the solution. The affinity depends on the size and charge of the solvated ion.

Ion pairs are formed when a cation and anion, which are present in a solution of an ionizable substance, come together to form a discrete chemical species. There are three distinct types of ion pairs, depending on the extent of solvation of the two ions. For example, magnesium sulphate exists as both contact and solvent-shared ion-pairs in seawater.
