2014年8月19日 · $$\ce{SbF5 + 2 HSO3F <=> H2SO3F+ + [SbF5SO3F]^{-}}.$$ Now this is a fairly large anion with a highly delocalised (due to symmetry constraints) charge. With excess of antimony pentafluoride, even larger anions can be formed, which is the case when used as a …

Question: antimony pentafluoride, SbF5, is a very strong Lewis acid and can be used in combination with HF to form a superacid solution. Predict the molecular geometry of SbF5 and draw its Lewis structure.

2018年8月6日 · $$\ce{SbF5 > AsF5 > PF5}$$ One simple argument could be the size of the $\ce{Sb}$-center: Because it is bigger than for example a $\ce{P}$-center it can accept more ligands. I couldn't find a more precise explanation or rationalisation.

2013年10月8日 · No water! $\ce{SbF5}$ is a tremendously strong Lewis acid: high oxidation state, fluorine electron withdrawal, and terrible mismatch of pi-orbital size inhibiting electron back donation. Solvo-cation, solvo-anion. $\ce{F^-}$ is a strong Lewis base.

2018年1月12日 · The 3D image of SbF5 is as follows: a side view a top view The bond dipole moments in vertical axis cancel out .Similarly the three Sb-F bonds positioned at 120 degrees to each other (top view image ) cancel out each other. Therefore SbF5 in non polar molecule.

Consider the reaction between HF and SbF5 to form the strong acid HSbF6.An acid-base buffer is able to resist changes in pH due to the addition of small amounts of strong acid or base to the system. An acid-base buffer ypically contains a weak acid and its conjugate base. 2nd attempt Part1 1 Feedback A buffer is prepared by mixing 25.2 mL of 0 ...

Answer to In this reaction: 2 HSO3F + SbF5 H2SO3F + +

Identify the lewis acids and bases for each of the following: a) SbF5 (L) + 2HF (L) = SbF6- + H2F+ b) 2CaO (s) + SiO2 (s) = Ca2SiO4 (s) Your solution’s ready to go! Our expert help has broken down your problem into an easy-to-learn solution you can count on.
