Fischer reaction
WebThe mechanism for carrying out the Fischer esterification process is as follows: Step 1: The oxygen in the carbonyl group will get protonated because of the use of an acid catalyst. Due to this, it will get activated for a nucleophilic attack from a molecule of ethanol. Step 2: After the alcohol has attacked the carbonyl carbon, there will be a ... WebKarl Fischer titration is an analytical technique to measure the amount of water contained in various samples, which may be solid, liquid or gaseous. This method was originally developed in the 1930s by German chemist Karl Fischer. Karl Fischer titration is based on a 1:1 reaction between iodine and water in the presence of sulfur dioxide and a ...
