... D2O (due to NH2) in addition to preence of singlet of two protons at 7.61 ppm ( S-CH2). The El-Mass spectra of compound (VI) shows prominent molecular ion peak and the fragmentation pattern are characterized by loss of NH-NH2 to produce the base peak. The new derivatives of quinoline was obtained wh ...

Acids, Bases, and Buffers
... Buffers are prepared by dissolving known amounts of a weak acid (HA) and the sodium or potassium salt of its conjugate base (NaA or KA) in a defined volume of water. When these compounds are mixed together and dissolved in water the following equilibrium is established: HA + H2O H3O+ + A– The meta ...
