Bromine thermodynamic propertie

Physical Properties. Sulfuryl chloride [7791-25-5] SO2CI2, is a colorless to light yellow Hquid with a pungent odor. Physical and thermodynamic properties are Hsted ia Table 7. Sulfuryl chloride dissolves sulfur dioxide, bromine, iodine, and ferric chloride. Various quaternary alkyl ammonium salts dissolve ia sulfuryl chloride to produce highly conductive solutions. Sulfuryl chloride is miscible with acetic acid and ether but not with hexane (193,194).

Bromine(Vll) shows even more thermodynamic instability than its Cl and I neighbours this is another example of the alternation of properties down the p-block groups brought about by the 3d contraction.

The hydride ion is a very strong base (pAT of hydrogen > 40) and hydride transfer to electrophihc centres in non-enzyme-catalysed reactions usually requires H either to be pushed off , as in metal hydride reductions or the Cannizzaro reaction, or to be pulled off by strong electrophiles, such as carbonium ions or bromine. The Cannizzaro reaction is another good example of how reaction at one centre in a molecule may completely modify the properties of an adjacent potential reaction site. Hydride transfer from an aldehyde group is thermodynamically unfavourable...
