Strong conjugate acid

The most important appHcation of metal alkoxides in reactions of the Friedel-Crafts type is that of aluminum phenoxide as a catalyst in phenol alkylation (205). Phenol is sufficientiy acidic to react with aluminum with the formation of (CgH O)2Al. Aluminum phenoxide, when dissolved in phenol, greatiy increases the acidic strength. It is beheved that, similar to alkoxoacids (206) an aluminum phenoxoacid is formed, which is a strong conjugate acid of the type HAl(OCgH )4. This acid is then the catalyticaHy active species (see Alkoxides, metal). [Pg.564]

These species are also unusual iu that they are extremely hydrophobic anions which form very strong conjugate acids. This unique combination of features leads to a number of potential uses such as the extraction of organic compounds from extremely dilute solutions and the isolation of metal cations, including the quantitative separation of radionucUdes, eg, Cs (192).

Similarly, strong bases produce weak corrugate acids in aqueous solutions and weak bases produce strong conjugate acids in aqueous solutions (Table 8.11). The strengths of acids, bases and their respective conjugates can be measured and expressed in terms of or pfQ (Chapter 18). [Pg.271]

Cations that are strong conjugate acids such as NHJ make a solution more acidic. [Pg.672]

All good leaving groups are weak bases with strong conjugate acids having low p a values. [Pg.237]

Student Annotation A strong conjugate acid is a weak Brizmsted acid. A strong conjugate base is a weak Brpnsted base. [Pg.698]

Because it accepts a proton from water to a small extent, what we refer to as a strong conjugate base is actually a weak Bronsted base. Therefore, every strong conjugate base has an ionization constant, K. Likewise, every strong conjugate acid, because it acts as a weak Bronsted base, has an ionization constant, K. ... [Pg.698]

The conjugate acid of a weak base is a strong conjugate acid, meaning that it acts as a weak Bronsted acid in water. [Pg.716]
