Qualitative Analysis, IR, NMR (Organic Chemistry) - Lab Report Example A resulting heterogeneous solution is a positive test for the a saturated hydrocarbon. Dissolve with ether then NaOH and Separate using the bottom layer then add HCl until pH ~7 (neutral) (top layer will be the other product). Add ether and separate the top layer (it’s the acid). IR available in attachment The temperature of carboxylic was relatively higher due to its double bond ranging from 143 to 153.8 Celsius displayed in the first and second trials of the solid acid, which depicts presence of carboxylic acid. Nevertheless, third trial temperature which ranges from 93.5 Celsius to 98.8 Celsius depicting the presence of molecule having two C=O groups associated by the corresponding symmetry. The two peaks within the region of the molecule has two C=O groups, which are not associated by the underlying symmetry that are depicted by the neutral product of the acid base extraction The carboxylic functional groups absorbed with the IR region are amidst 1100 to 1700cm-1. Moreover, main peaks within carboxylic groups are understood via appraisal of the values of the compounds as depicted in the table for NMR graph (Ha Harris, pp.289-345). The absorption of the polar groups are removed towards the lower frequencies and are normally widened due to the hydrogen bonding such as hydroxyl and corresponding amino groups (Rris, pp. 567-659). There two types of IR, from the acid and from the neutral similarly with the NMR, there are C13 and H1 from acid (with DMSO) and other product (with CDCl3). IR spectrum with one peak found within the carboxylic region probably one C=O group is present. The C=O region distances 1608.86 cm-1 having the sharpest peaks, which are many cm-1 wide. Thus, the two C=O groups could be present with the similar position by concurrence. The molecule are two C=O groups associated to the symmetry. The two peaks within the region probably the molecule has two
