Concept introduction:
Amines are given common names by listing the alkyl groups attached to nitrogen atom in alphabetical order followed by the suffix –amine. The prefixes di and tri are used when there are more than one identical groups present. According to IUPAC rules, the longest chain is determined and the ending of the alkane is changed from –e to –amine. The position of the amino group is indicated by a number and the prefix N is used if the substituents are attached to nitrogen atom.

- Determine the pH of solution of HC3H5O2 By constructing an ICE table writing the equilibrium constant expression, and using this information to determine the pH. The Ka of HC3H5O2 is 1.3 x 10-5arrow_forwardDetermine if the following salt is neutral, acidic or basic. If acidic or basic, write the appropriate equilibrium equation for the acid or base that exists when the salt is dissolved in aqueous solution. If neutral, simply write only NR. Be sure to include the proper phases for all species within the reaction LiNO3arrow_forwardAn unknown weak acid with a concentration of 0.410 M has a pH of 5.600. What is the Ka of the weak acid?arrow_forward

Next, record any regiochemistry or stereochemistry considerations relevant to the reaction. You should also record any key aspects of the mechanism, such as forma- tion of an important intermediate, as a helpful reminder. You may want to keep track of all reactions that make carbon-carbon bonds, because these help you build large molecules from smaller fragments.
