From this experiment, we ended up with a percent yield of 79.3 % which is a good amount. Some possibly explanation for only have obtained 79.3% yield is the fact that during the reflux, the reaction started to boil exceedingly, so we lowered the temperature, to lessen the strength of the boil. However, the reaction stopped boiling and we had to raise the temperature to continue the experiment, which...
