During a titration, it is desired to calculate the concentration of ammonium hydroxide using sulfuric acid as the titrant. The relevant titration reaction is given below. (1.jpg) In the titration using 0.3 M sulfuric acid in the presence of methyl orange, 20 cm3 of ammonium hydroxide was taken from the sample. Since 40 cm3 of sulfuric acid is consumed during the titration, calculate the concentration of ammonium hisroxide in terms of molarity.
Neurotransmitters are small molecules that are produced by the body to send messages from one neuron to another. Noradrenaline (also called norepinephrine) and serotonin are neurotransmitters that act in the central nervous system. A synthetic compound called PMPEA has effects that are similar to both noradrenaline and serotonin in the spinal cord. (Tetrahedron Lett. 2011, 52, 4182-4185.) Deduce the structure of PMPEA, given its molecular formula (C9H13NO) and the following 1H NMR spectral data: 1.1 ppm (2H, broad singlet) 2.7 ppm (2H, triplet) 2.9 ppm (2H, triplet) 3.8 ppm (3H, singlet) 6.8 ppm (2H, doublet) 7.1 ppm (2H, doublet) Draw Your Solution
