WebWorked example: Identify the functional groups in the molecule C6H12O2, using the infrared spectrum given below. (2 marks) Infrared (IR) Spectroscopy. Answer: Signal at 3230-3350 shows an O-H (alcohol) (1) and C=O at 1680-1750 (1) There are separate -OH and C=O bonds in the molecule, so it is not a carboxylic acid. WebAnswer. IR spectrum A is propanone and spectrum B is propan-2-ol.. In IR spectrum A the presence of a strong, sharp absorption around 1710 cm-1 corresponds to the characteristic C=O, carbonyl, group in a ketone.. In spectrum B the presence of a strong, broad absorption around 3200-3500 cm-1 suggests that there is an alcohol group present, which …

WebUsing an Arrhenius plot: A graph of ln k against 1/ T can be plotted, and then used to calculate Ea. This gives a line which follows the form y = mx + c. The graph of ln k against 1/T is a straight line with gradient -Ea/R. From the graph, the equation in the form of y = mx + c is as follows: WebAmines react with HC l to form amine salts, such as ethylammonium chloride. C2H5NH2 + HCl → C2H5NH3+Cl-. base acid salt. Like ammonium salts, amine salts are soluble ionic compounds, so when the alkyl group is small they are water soluble but become less so as the carbon chain increases.
