HSAB theory is also useful in predicting the products of metathesis reactions. In 2005 it was shown that even the sensitivity and performance of explosive materials can be explained on basis of HSAB theory. [2] Ralph Pearson introduced the HSAB principle in the early 1960s [3] [4] [5] as an attempt to unify inorganic and organic reaction ...
Hard metal cations, as classified by HSAB theory, tend to form N-bonded complexes (isothiocyanates), whereas class B or soft metal cations tend to form S-bonded thiocyanate complexes. For the isothiocyanates, the M-N-C angle is usually close to 180°. For the thiocyanates, the M-S-C angle is usually close to 100°.
[2] [17] The Brønsted–Lowry acid–base theory was published in the same year. The two theories are distinct but complementary. A Lewis base is also a Brønsted–Lowry base, but a Lewis acid does not need to be a Brønsted–Lowry acid. The classification into hard and soft acids and bases (HSAB theory) followed in 1963.
The ludic fallacy, proposed by Nassim Nicholas Taleb in his book The Black Swan , is "the misuse of games to model real-life situations". [1] Taleb explains the fallacy as "basing studies of chance on the narrow world of games and dice". [2] The adjective ludic originates from the Latin noun ludus, meaning "play, game, sport, pastime". [3]
Before we explain this incorrectness, let us examine a little of the principles of HSABs: Pearson is the one who created the HSAB theory, based on the principle: Hard acids can react well with hard bases, amd soft acids with soft bases. The following is a table of common HSABs. Blnguyen (bananabucket) 03:53, 21 November 2006 (UTC)
Oxophilicity is often stated to be related to the hardness of the element, within the HSAB theory (hard and soft (Lewis) acids and bases), but it has been shown that oxophilicity depends more on the electronegativity and effective nuclear charge of the element than on its hardness. [1]

According to hard/soft acid/base (HSAB) theory, sulfur is a relatively soft (polarizable) atom. This explains the tendency of thiols to bind to soft elements and ions such as mercury, lead, or cadmium. The stability of metal thiolates parallels that of the corresponding sulfide minerals.
