There are a number of examples of acid-base chemistry in the culinary world. The diamines are condensed with phosgene to give methylene diphenyl diisocyanate, a precursor to urethane polymers. Aniline (C6H5NH2) is a weak base and can be represented by the following equation: C6H5NH2 + H2O C6H5NH3+ + OH-The Kb expression for aniline is: Kb = [C6H5NH3+][OH-] / [C6H5NH2] . When the conjugate acid and the conjugate base are of unequal strengths, the solution can be either acidic or basic, depending on the relative strengths of the two conjugates. When C6H5NH3+ reacts with H2O, it gives off a positively charged Hydrogen ion that forms hydronium ion (H3O+). C6H5NH3+, as the acid, is a proton donor. Today, the name of BASF, originally Badische Anilin- und Soda-Fabrik (English: Baden Aniline and Soda Factory), now the largest chemical supplier, echoes the legacy of the synthetic dye industry, built via aniline dyes and extended via the related azo dyes. Below are some classes of its reactions. Strong acid. The principal use of aniline in the dye industry is as a precursor to indigo, the blue of blue jeans. This is the most complex of the four types of reactions. Why is my internet redirecting to gslbeacon.ligit.com and how do I STOP THIS. The value of Ka for this acid is not listed in Table E1, but we can determine it from the value of Kb for aniline, C6H5NH2, which is given as 4.6 1010 : \[\mathrm{\mathit{K}_a(for\:C_6H_5NH_3^+)\mathit{K}_b(for\:C_6H_5NH_2)=\mathit{K}_w=1.010^{14}} \nonumber \], \[\mathrm{\mathit{K}_a(for\:C_6H_5NH_3^+)=\dfrac{\mathit{K}_w}{\mathit{K}_b(for\:C_6H_5NH_2)}=\dfrac{1.010^{14}}{4.610^{10}}=2.310^{5}} \nonumber \].

Createyouraccount. Label Each Compound With a Variable. HS? It has one more H atom and one more + charge (-1 + 1 = 0). The observed geometry reflects a compromise between two competing factors: 1) stabilization of the N lone pair in an orbital with significant s character favors pyramidalization (orbitals with s character are lower in energy), while 2) delocalization of the N lone pair into the aryl ring favors planarity (a lone pair in a pure p orbital gives the best overlap with the orbitals of the benzene ring system). To generate the mono-substituted product, a protection with acetyl chloride is required: The reaction to form 4-bromoaniline is to protect the amine with acetyl chloride, then hydrolyse back to reform aniline.
