WebThe F–S–F bond angle in the SF 3 + cation is expected to be slightly smaller than 109.5° because the repulsion between the nonbonding pair of electrons and the S–F bonding pairs of electrons “squeezes” the F–S–F bond angles together slightly. One point is earned for stating that the angle is smaller, with justification. Being highly dissociated, CsF is a more reactive source of fluoride than related salts. CsF is an alternative to tetra-n-butylammonium fluoride (TBAF) and TAS-fluoride (TASF). As with other soluble fluorides, CsF is moderately basic, because HF is a weak acid. The low nucleophilicity of fluoride means it can be a useful base in organic chemistry. CsF gives higher yields in Knoevenagel condensation reactions than KF or NaF.
